6.2. Consider a common telephone channel with the bandwidth limited from 300 Hz to 3400 Hz modeled by an ideal band pass filter (zero attenuation between 300 and 3400 Hz, complete rejection of signals outside the 300 - 3400 Hz range). You apply a square wave of 400 Hz, 1 Vpp amplitude, 50% duty cycle to the input. 6.2.1. How would the signal waveform look like at the output of this channel (time domain)? Draw an approximate sketch! 6.2.2. How would the spectrum of the signal at the output of this channel look like? Sketch!
