To measure the period of a pulse waveform, you must use( )
A: a DMM
B: a logic probe
C: an oscilloscope
D: a logic pulser

举一反三
- if the period of a pulse waveform increase, the frequency alse increases
- Each time a pulse is applied to the clock input of a flip-flop, its outputs change their logic state from high (logic 1) to low (logic 0) or vice versa.
- in a certain digital waveform, the period is twice the pulse width . the duty cycle is
- In English, logic is implied. Therefore we should avoid the use of logic markers.
