Here is the exercise I am working on.
Use the window design method with the Kaiser window to design a linear phase high pass FIR filter of minimum order that meets the following specification: $\omega_P=0.8\pi$,$\omega_S=0.7\pi$, maximum pass band error=0.1dB, minimum stopband attenuation = 75dB ( you can use Matlab but you need to ensure that the final filter meets the spec. Recall that for window design methods, the errors in pass and stopband will be equal. Be sure to take it into account in your answer)
I know how to design a FIR filter using window method. What I do not understand is the last two sentences. What is "the errors in pass and stopband"? What it mean by "take it into account"?
