Question

4.18 Let h(n) be a (real-valued) FIR impulse response, not necessarily linear-phase. Then the impulse response defined by convolving h(n) with its time-reversed version is always a linear-phase FIR filter. In other words, p(n) := h(n) * h(-n), is a linear-phase FIR impulse response. The question is: which of the four linear-phase FIR filter types can p(n) be?
