What is the function of an LNB for satellite television?
LNB stands for Low Noise Block. This device amplifies the weak incoming signal from the satellite and converts it to a signal that is usable by the television.
What is an amplifier repeater?
A repeater that does not distinguish between noise and signal; it amplifies both.
Is repeater an amplifier?
A repeater that does not distinguish between noise and signal; it amplifies both.
How the differentiation of the signal amplifies the noise?
any signal, be it be noise is composed of sinusoids...so when one differentiates sinWt with respect to time it becomes WcosWt ...hence the signal gets multiplied by W..
What is the device used to improve signal-to-noise ratio called?
A preamp A preamp.
What is logarithmic quantizer or quantization?
In logarithmic quantization, one does not quantize the incoming signal but log of it to maintain signal to noise ratio over dynamic range. Dr Inayatullah Khan
What is an autocorrelator?
An autocorrelator is a device which modifies a signal with a delayed copy of itself in order to detect any periodic signal hidden in the noise.
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.
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.
Noise reduce from signal?
noise reducing from signal by some method?
What is an amplifier and what type of transmission signals does it affect?
An amplifier is a device that increases the strength of a signal. There are many, many different kinds of amplifiers, making many kinds of signals stronger. A stereo amplifier takes the tiny signal coming off of a music device, such as a radio tuner or an iPod, and amplifies it until it is powerful enough to cause the stereo speakers to make noise. A megaphone is just a cone with a hole in the tip that you can hold in front of your mouth, but it amplifies the sound waves coming from your vocal cords. Cable TV companies put amplifiers into their cable networks that amplify the TV signal, so that it doesn't fade away into static before it reaches your TV. In computer networking, we usually call them "repeaters". A repeater takes a packet that's travelled about as far as it can before it turns into static, amplifies it so it can be properly read, then makes a new copy and sends it down the next section of wire.
