How bit rate is 2 times of baud rate in Qpsk?
Although QPSK (quadrature phase shift keying) refers to an instance when two bits are processed at once, this does not mean that the actual bit rate is twice that of the baud rate.
What is the difference between PSK and QPSK?
in psk,we use only single type of phase shift for a bit transition. in qpsk,we use 4 types of phase shifts for a bit transition.
What is the difference between BPSK and QPSK?
Binary PSKQPSK.1. Two different phases are used torepresent two binary values.1. Four different phases are used to represent two binary values.2. Each signal element represents only one bit.2. Each signal element representstwo bits
What is bit error rate?
In a computer system, the bit error rate is based on the percentage of bits transmitted and received compared to those that resulted in error.
What is the typical bandwidth of a satellite transponder?
38 MHz. digital bit-rates vary depending on compression, modulation, typically QPSK. Expect at least 30 Mbps.
Does light travel faster underwater than in air?

Give an example of a signal for each what conditions the baud rate is equal to the bit rate the baud rate is greater than the bit rate and the baud rate is less than the bit rate?
Basically the baud rate can never be greater than the bit rate. Baud rate can only be equal or less than the bit rate. However, there are instances that baud rate maybe greater than the bit rate. In Return-to-zero or Manchester encoding, where there are two signaling elements, the baud rate is twice the bit rate and therefore requires more bandwidth.
What is bit rate of Ethernet when Manchester encoding is used?
bit rate is half the baud rate
Difference between bit rate and bit period?
Bit rate is related to the maximum frequency being sent over a channel; it is roughly twice this maximum frequency. Bit period is the time it takes to send a bit; it is 2/(bit rate).
How you can Find the maximum data rate of a noiseless 4-kHz channel-using Analog encoding eg QPSK with 2 bits per sample?
for 4KHz then for noisy channel using Shannon theorem, sampling rate will be 8K samples/sec. So with 2 bit encoding, 2 bits are sent per sample. So the data rates is 8000 samples / sec * 2 bits = 16000bits / sec = 16kbps.
What is difference between baud rate and frequency?
baud rate is the rate of symbol changes...symbol can be of 1 bit, 2 bit , 3 bit etc.... Where as frequency is the inverse of rate of lowest unit in a digital transimission...
What is the bit rate for the signal in which 8 bit lasts 16 ns?
Bit rate = 8 / (16 * 10-9) bits/second
