Module 2: Signals / The AD Board 07/07/2015 Signal Analysis - Recap Draw 3 more periods of the square wave Boston University Slideshow Title Goes Here What is the frequency of this waveform? Label the amplitude Label the pulse width What is the duty cycle of this square wave? Draw another signal with 25% duty cycle Draw another signal with a phase shift period Amplitude (Pk to Pk) t 1s Pulse Width Phase Shift 2
