Question

A cellular system uses fdma with spectrum allocation of 12.5 mhz in each direction, a guard band at the edge of the allocated spectrum of 10 khz, and a channel bandwidth of 30 khz. Find out number of channels available.

Answer 1

Explanation:

The combined effect of resistance R, inductive reactance XL, and capacitive reactance XC is defined to be impedance, an AC analogue to resistance in a DC circuit. Current, voltage, and impedance in an RLC circuit are related by an AC version of Ohm’s law:
