Digital Download Switch

Analog switch integrated chips (ICs), when turned on, will conduct both analog and digital signals from the input pin to the output pin. Digital switches can only accept digital signals and duplicate the logic level on the input pin at the output pin. When the digital switch is turned off, it returns to a default logic state.

An analog switch acts like a solid-state relay (i.e., with no moving parts). Analog switches can also isolate devices at their terminals when the analog switch is OFF. When ON, they conduct both analog and digital signals, regardless of the direction in which the signal is traveling. The switch control input for both kinds of switches is usually a digital signal input (called an input select), although other control triggers can be used to make specific applications easier to implement.

Analog switches are able to pass or isolate both analog and digital signals, but digital switches can only pass or isolate digital signal lines. Both are used instead of mechanical switches for convenience, reliability, and their small size as compared to mechanical switches.

Both types of switches are typically manufactured as integrated circuits, often in packages with multiple (individual) switches. Multiplexors are also switches, but act more like a train station with multiple trains feeding via railroad switches onto one track, and is a separate topic.

The remainder of this article concerns analog switches. For analog switches, the switching portion of the device is made up of a couple of transistors. In Figure 1, the transistors are MOSFETs; one is a P-channel MOSFET and the other is N-channel. MOSFETs make perfect switching devices and are often used in power applications.

Solid-state switches are much smaller than mechanical devices. They are fast, easy-to-use, and use less power than relays or other electrically controlled switches. However, no switch is perfect in real life. The ideal switch would transmit a signal without no changes to the signal whatsoever. However, actual analog switches will generate ground bounce noise and demonstrate propagation delay. All of the issues with common parameters are going to be present with solid-state analog switches; for instance, the on-state drain-to-source resistance that is a common parameter when switching MOSFETs will be present in switching in an analog switch. One downside to MOSFETs is that they are not actually perfect; one imperfection is some resistance associated with turning on the MOSFET. RON, or more specifically RDS(on), is the total resistance in the path from source-to-drain and is made up of a series of resistances that traverses the path of current flow through the MOSFET switch. RDS(on) is the basis for a maximum current rating of the MOSFET and is also associated with current loss, thus a lower RDS(on) is preferred.

Issues like input capacitance and on-resistance can cause insertion loss (loss of power due to insertion in a transmission line) and harmonic distortion. Such issues are quite typical in electronic circuits, however, and analog switches are not immune.

Several semiconductor manufacturers offer a variety of analog switches and have selection guides that can help narrow down to the best choice. Major manufacturers who market analog switches are Maxim Integrated, Analog Devices, Microchip, Texas Instruments, IDT, ON Semiconductor, Vishay, ST Microelectronics, Intersil, NXP, ROHM Semiconductor, and others.

If you do not have access to the original console, you can still transfer your Nintendo Account and digital games to a different Nintendo Switch console and make that console your account's primary console. Follow these steps to complete this process.

I am soon to be owner of a new switch. You may've read my old post "how to convince my wife". So yeah, I've suceeded and now will be soon to be owner of a new switch, so wanted to gather some opinions on this topic. I know some basic benefits and negatives, I know how each of the choices work. What I wanted to gather is your personal preference and why? And maybe which path would you choose, if you could start fresh? Thanks everyone.

Disclaimer, this may not work 100% on all devices, for example if turn the switch on Physical, then off via digital, then do a physical off, the devices I have do NOT report the physical off because it is already off. If the device supports CentralScene might be able to capture the on/off physical presses via buttons instead of the state. Maybe I will do another example using the buttons for the physical. Or if anyone has any ideas how to do this better let me know.

Here is the complicated part, in another rule that triggers on any switch event I have two local variables to calculate the time difference from the last physical change. If its less than 500ms I assume this rule was triggered physical, and if > 500 I assume it was a digital trigger. The "Laundry Physical" and "Laundry Digital" are virtual switches. The delay of 0.1 seconds is to make sure the other rules has time to trigger and update the global var if it was a physical change.

The digital television transition, also called the digital switchover (DSO), the analogue switch/sign-off (ASO), the digital migration, or the analogue shutdown, is the process in which older analogue television broadcasting technology is converted to and replaced by digital television. Conducted by individual nations on different schedules, this primarily involves the conversion of analogue terrestrial television broadcasting infrastructure to digital terrestrial (DTT), a major benefit being extra frequencies on the radio spectrum and lower broadcasting costs, as well as improved viewing qualities for consumers.

Before digital television, PAL and NTSC were used for both video processing within TV stations and for broadcasting to viewers. Because of this, the switchover process may also include the adoption of digital equipment using serial digital interface (SDI) on TV stations, replacing analogue PAL or NTSC component or composite video equipment. Digital broadcasting standards are only used to broadcast video to viewers; Digital TV stations usually use SDI irrespective of broadcast standard, although it might be possible for a station still using analogue equipment to convert its signal to digital before it is broadcast, or for a station to use digital equipment but convert the signal to analogue for broadcasting, or they may have a mix of both digital and analogue equipment. Digital TV signals require less transmission power to be broadcast and received satisfactorily.[1]

The switchover process is being accomplished on different schedules in different countries; in some countries it is being implemented in stages as in Australia, Greece, India or Mexico, where each region has a separate date to switch off. In others, the whole country switches on one date, such as the Netherlands.[2] On 3 August 2003, Berlin became the world's first city to switch off terrestrial analogue signals.[3] Luxembourg was the first country to complete its terrestrial switchover, on 1 September 2006.[4] e24fc04721
