Electrical Engineering

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

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

3) List all the frequencies that emerge from a mixer that is fedwith an incoming frequency of 107.1 MHz and another frequency of96.4 MHz

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

FS = 90 MHz             FLO= 100 MHz          FIMAGE=?

5) List all the frequencies that emerge from a mixer that is fedwith an incoming frequency of 107.1 MHz and another frequency of96.4 MHz. Which frequency is normally filtered out in a modernreceiver?
