What is AWGN channel?
An AWGN channel adds white Gaussian noise to the signal that passes through it.
What is the relation of signal to noise ratio and signal bandwidth?
C=blog(1+s/n)
What is the necessary of using hamming windowing in signal processing?
To remove the noise
What are the disadvantages of delta modulation?
1. The bandwidth for transmission of PAM signalis very very large compared to its maximum frequency content. 2. The Amplitude of PAM Pulses varies accordingly to modulated signal. Therefore interference of noise is maximum for the PAM signal and this noise cannot be removed very easily. 3. Since amplitude of PAM signal varies, this also varies the peak power required by the transmitter with modulating signal.
What is a noise generator used for?
A noise generator produces electrical signals in both audio and video format. These are used for troubleshooting purposes in signal circuits for amplifiers and televisions.
How does noise affect an analog signal?
A: Noise effect an analog signal by adding or subtracting from the signal
What is the purpose of white noise?
White noise sounds like a hiss. It can be used in the sythesis of musical instruments or sound effects. It is random noise and can be used for signal analysis.
Which factor affect data rate of a link?
the bandwidth and the signal to noise ratio
What type of distortion always occurs on an analog connection?
Analog connections can experience distortion due to factors such as noise, attenuation, and interference. These distortions can affect the quality and clarity of the signal being transmitted over the analog connection.
What do engineers use the signal to noise ratio for?
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.
What is tv white noise?
White noise is also called "snow" and it looks like a snow storm on the screen. It is the result of an analog receiver not getting a signal and it can be compared to the hiss from a radio when it loses its signal. Modern televisions often suppresses the noise and digital televisions do not suffer from it at all.
Signal to noise ratio?
Noise signal is any signal which interferes with the main signal and does not give any important information.Signal should always be twice to that of noise.
What is AWGN channel?
An AWGN channel adds white Gaussian noise to the signal that passes through it.
Noise reduce from signal?
noise reducing from signal by some method?
What is white noise?
White noise is random sound that contains an equal amount of all the frequency components across the spectrum one is testing. It sounds sorta like the hiss one hears when a television is tuned to a blank channel (if the television doesn't automatically mute the sound when no signal is present, however). If one has white noise and examines the signal level of, say, the 55 cycle per second signal component, it will be the same as, say, the 927 cycle per second signal component, or the 2651 cycle per second signal component.

During transmission of a signal with a data rate of 10 kbps suppose that noise occurs for 0.001 seconds How many bits can the noise affect?
10 bits
When was Signal to Noise - novel - created?
Signal to Noise - novel - was created in 1998.
