What is frequency response in DSP?

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.

How do you find the finite difference coefficient?

f ( b ) = f ( a ) + f ′ ( a ) 1 ! ( b − a ) + f ″ ( a ) 2 !
