What is signal subtraction?
This test is used to determine if two signals are identical to each other. If the signals are identical, then by subtracting one from the other the result is a signal with an amplitude of zero.
How does spectral subtraction work?
Spectral subtraction is a method for restoration of the power or the magnitude spectrum of a signal observed in additive noise, through subtraction of an estimate of the average noise spectrum from the noisy signal spectrum.
What is frequency response in signal processing?
In signal processing and electronics, the frequency response of a system is the quantitative measure of the magnitude and phase of the output as a function of input frequency.
What is frequency response of a system what is its significance?
A frequency response describes the steady-state response of a system to sinusoidal inputs of varying frequencies and lets control engineers analyze and design control systems in the frequency domain.
