In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

Learners examine the fundamentals of a pulse train. Concepts such as time on, time off, duty cycle, period, and frequency are covered.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

This screencast shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

In this animated activity, learners practice listening and counting the apical pulse of adults, children, and infants.

In this animated object, learners examine the recommended procedure for troubleshooting a defective JK flip-flop using a logic pulser and probe.
