Question

if aperiodic signal has a bandwidth of 100hz and the highest frequency is 140hz then findout lowest frequency

Answer 1

Ans. 1. 100 ms = 100 * 10 ^(-3) s = 100 * 10^(-3) * 10^6 micro sec = 10^5 microseconds 2. Period of signal = 100 ms = 10^(-1)s frequency = 1/time period = 1/10^(-1) Hz = 10 Hz or 10^(-2) KHz 3. As, 1 cycle = 360 degrees 1/6 cycle = 60 degrees = 60 * 2pi/3 radian = 1.046 rad 4. Let fh be highest...
