I googled a bit, but couldn't find any good apps that help assist in the testing of an audio device (like an MP3 player). I would like to test the THD and the SNR of the device. Are there any good ...

Fig 1. In capacitive touchscreens, the signal in SNR is the measured amount of change in mutual capacitance as a direct result of finger capacitance. Finger capacitance depends on the sensor cover ...

Theoretically, the SNR (signal-to-noise ratio) of an ADC is equal to (6.02N+1.76) dB, where N equals the number of ADC bits. Although I’m a little rusty with my algebra skills, I think that the SNR ...
