Designing a High-Pass FIR Filter using the windowing method
Finite Impulse Response (FIR) filters are of great interest in digital signal processing tasks because they have a linear phase response and do not cause many distortions to the filtered signal. Furthermore, unlike an Infinite Impulse Response (IIR) filter, the FIR filter is non-recursive, i.e. it has no feedback (it uses only samples of the input signal) and, consequently, is a naturally stable filter.
