Effect of feedback on stability and sensitivity?
Feedback can cause a lack of stability. However, negative feedback can actually reduce distortion, noise, and sensitivity to the noise.
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
Why positive feedback is not used in amplifier?
positive feedback makes regeneration of the input signal,which creates more noise. ANSWER: To feedback positive voltage will do nothing for noise or any other reason but force the amplifier to saturate to the hi rial or the low rail of the power supply
Why is negative feedback used in high gain amplifier?
A: Well for one thing if it is positive feedback the amplifier will saturate to one one side of the power buss or the other. An operational amplifier open loop gain can be 90Db which a tremendous gain so some negative feedback is necessary to reduce the gain and make the amplifier behave in the linear region for amplification
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 signal degradation in data communications?
A downward change in signal strength where the wave 'Fades' from distance lmitations, interference, noise or EMI.
When was Signal to Noise - novel - created?
Signal to Noise - novel - was created in 1998.
When was Signal to Noise - comics - created?
Signal to Noise - comics - was created in 1992.
How many pages does Signal to Noise - novel - have?
Signal to Noise - novel - has 371 pages.
What are the factors affecting signal to noise ratio?
If the SNR is too low, the signal cannot be distinguished from the noise. The signal must be boosted, or noise must somehow be removed.
