Question 262easy
Long distance communication system via satellite uses frequency in the range
Question 263easy
A system has poles at 0.01 Hz, 1 Hz and 80 Hz; zeros at 5 Hz and 200 Hz. The approximate phase of the system response at 20 Hz is
Question 264easy
A mW video signal having a bandwidth of 100 MHz is transmitted to a received through a cable that has 40 dB loss, lithe effective one-sided noise spectral density at the receiver is 10-20 Watt/Hz, then the signal-to-noise ratio at the receiver is

Question 265easy
Two sinusoidal signals of same amplitude and frequencies 10 kHz and 10.1 kHz are added together. The combined signal is given to an ideal frequency detector. The output of the detector is
Question 267easy
During transmission over a certain binary communication channel, bit errors occur independently with probability p. The probability of AT MOST one bit in error in a block of n bits is given by

Question 268easy
In a GSM system, 8 channels can co-exist in 200 kHz bandwidth using TDMA. A GSM based cellular operator is allocated 5 MHz bandwidth. Assuming a frequency reuse factor of ?5 , i.e. a five-cell repeat pattern, the maximum number of simultaneous channels that can exist in one cell is
Question 269easy
In a Direct Sequence CDMA system the chip rate is 1.2288 x 106 chips per second. If the processing gain is desired to be AT LEAST 100, the data rate
