What is friis equation?
Friis equation involves noise factor and gain, the expression is used to calculate the overall noise factor of a given cascaded system, for example a cascaded amplifier with many stages. below shows the expression for calculating the total noise factor using friis equation. Fn = F1 + (F2 - 1 / G1) + (F3 - 1 / G1G2) + (F4 - 1 / G1G2G3) ....... and so on Where: Fn = The total noise of all stages together F1 = The noise factor of stage 1 F2 = The noise factor of stage 2 F3 = The noise factor of stage 3 G = Gain of respective stage Friis equation involves noise factor and gain, the expression is used to calculate the overall noise factor of a given cascaded system, for example a cascaded amplifier with many stages. below shows the expression for calculating the total noise factor using friis equation.

How the noise is overcome with the help of positive feedback amplifier?
A: With positive feedback the amplifier is saturated one way or the other in a quiescent state no signal or noise input can effects its output
What is a satellite LMB?
Have you ever wondered what is an LNB and what is an LNB LO frequency ? Here is some information about LNBs that I hope will help explain matters.The abbreviation LNB stands for Low Noise Block. It is the device on the front of a satellite dish that receives the very low level microwave signal from the satellite, amplifies it, changes the signals to a lower frequency band and sends them down the cable to the indoor receiver.The expression low noise refers the the quality of the first stage input amplifier transistor. The quality is measured in units called Noise Temperature, Noise Figure or Noise Factor. Both Noise Figure and Noise Factor may be converted into Noise Temperature. The lower the Noise Temperature the better. So an LNB with Noise Temperature = 100K is twice as good as one with 200K.The expression Block refers to the conversion of a block of microwave frequencies as received from the satellite being down-converted to a lower (block) range of frequencies in the cable to the receiver. Satellites broadcast mainly in the range 4 to 12 to 21 GHz.
Which device amplifies the incoming signal and noise?
Amplifier repeater
Where should I place the noise suppressor in my pedal chain to effectively reduce unwanted noise?
To effectively reduce unwanted noise in your pedal chain, place the noise suppressor towards the end of the chain, just before the amplifier. This will help eliminate any noise picked up by the pedals before it reaches the amplifier.
Why to have a filter before and after a low noise amplifier?
To cut off unwanted frequencies, unwanted frequencies are called noise.
Why noise of Low Noise Amplifier increases if you want to increase gain of it?
That is the case with all amplifiers. The noise floor is always lifted when the gain is increased.
What is an amplifier repeater?
A repeater that does not distinguish between noise and signal; it amplifies both.
What type of antenna is used in cellphone for FM?
LNA - Low Noise Amplifier
