- 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
- 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?
