Fundamental frequency of the spectrum of the square wave
A square wave has amplitude 0 volts and 1.0 volts, and a period of 0.5 ms.
a. What is the frequency of the square wave?
b. What is the fundamental frequency of the spectrum of the square wave?
c. What is the magnitude of the fundamental frequency component of the spectrum of the square wave?
d. The square wave is passed through an ideal rectangular low pass filter that completely attenuates all frequencies higher than 3 kHz. What is the spectrum at the output of the filter?
