Which of the following is the main advantage of PCM system?
-
BPSK stands for
-
If a dipole is meant for a frequency of 1 MHz, the length of each rod is about
-
Consider the following statements:
In a radar system having a high value of the ratio (antenna diameter)/wavelength- the maximum range is large
- good target discrimination is achieved
- capture area is increased
- target acquisition is difficult
-
Assertion (A): The maximum range of a radar is proportional to fourth root of the peak transmitted pulse power.
Reason (R): Radar signals are subjected twice to inverse square law.
-
Cross talk is due to reception of portions of a signal from one channel into another.
-
If there are M equally likely and independent messages and M = 2N where N is an integer, the information in each message is equal to
-
A radar beacon is a small radar set having a receiver, a separate transmitter and an antenna.
-
In the above case the total power in the modulated wave double sideband, suppressed carrier AM will be
