DSP (Digital Signal Processing Workflow)

Explain the signal journey that you are experiencing now on Zoom, that is. I am in my house, you are somewhere else. How does my image and voice get to you? How does your image and voice get to me? Illustrate this from the perspective of the signal, what is the input, what is the output? Which devices are being used? How are they connected to each other? Etc. Use the jamboard linked below.

The first flash lab explored the signal journey that is experienced by students when they are on a live zoom call with their professor along with classmates online. To begin each individual (student & professor) uses a device either phone or computer to connect to the call. These devices are equipped with a camera and microphone which ideally both work. When an individual on the call speaks into their microphone, analog data is recorded. When an individual has their camera on, digital data is recorded. An analog to digital converter is used to convert the analog signal to a digital signal such that the microphone and camera data can be processed in a digital system on their computer on a continuous cycle. Next, this digital data is processed through an internet router, sent through the cloud, to a satellite to reach the other individuals routers on the call and processed within their router. They will receive the signals on their computer where a digital to analog converter will be used to convert the signals back to analog data for their speakers to transmit sound and to their computer screen for their computer to illustrate visual images of the person sent from their camera. The image below is a more clear representation of this process.
