Summary
[edit]DescriptionATmega8 ADC sampled “knocks” at 450 Hz rate, directly.svg |
English: A digitization of “knocks” taken using ATmega8 built-in ADC at 450 Hz sampling rate. The signal was picked up directly from a piezoelectric buzzer (shunted with a 680 kΩ resistor) used as a microphone. Note the relatively large signal falling times, resulting from the high internal resistance of the buzzer not allowing for the ADC-internal “store and hold” capacitor to discarge in timely manner. |
