  1. A collector-modulated power has a supply voltage of 48V and an average collector current of 600 mA. Determine: a) the input power to the transmitter? b) the modulating signal power needed to produce 100% modulation?

2) …. receivers convert all incoming signals to a lower, fixed frequency.

3) List all the frequencies that emerge from a mixer that is fed with an incoming frequency of 107.1 MHz and another frequency of 96.4 MHz

  1. What is the Image Frequency that results from the signal frequency and local oscillator frequency?
