Fast Signal Sampling (Part 1)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 11, 12 In an early post, I described an electronic interface which adjusts the level electret microphones to the level of Arduino’s ADC. We need now to accurately sample the signal, using enough samples to get a nice representation of the captured […]
