Online Circuit Simulation
Falstad Circuit Simulator and Tinkercad are used in the online lab sessions during the Covid-19 pandemic. Check out the interactive simulator here and try out some fun exercises mentioned below.

Fun Exercises with Audio Signals
(Know more about Audio Signals and Frequency Visualization here.
To view frequency content in the Falstad Simulator, go to Plot Properties > Plots > Show spectrum. The present frequency components should appear as a well-defined peak in the frequency spectrum.

The first six seconds of the Ed Sheeran song 'Shape of You' contain a high-pitch feedback sound. Design a filter to remove this sound. (Hint: Use frequency-visualization tools of the Falstad simulator for an Audio Input.)

Every key on a phone's dial pad is represented by a particular tone. Each tone is simply the sum of two sine waves (i.e. two frequencies). This system is called the Dual-tone Multi-frequency (DTMF) signaling system, and the frequency chart of each digit is shown below.
You are a detective on a case where you have been listening in on phone calls of a suspect (with a record-only warrant). Identify the phone number of the person this suspects calls only from the audio of the DTMF tones.
