Define the terms fundamental frequency, spectrum, and absolute bandwidth of a signal. A signal has a fundamental frequency of 1000 Hz. What is its period? Assume the signal has a peak amplitude of 1 Volt and that the instantaneous power is equal to the square of the voltage, then compute the average power of the fundamental frequency component of the signal. When the signal is transmitted, the measured power at the receiver is 0.25 W. Express the power loss in decibels.
