The frequency response of an ideal low-pass filter is 1 -1/2 < w <1/2 0 otherwise in

Question:

The frequency response of an ideal low-pass filter is

1 -1/2 < w <1/2 0 otherwise in (–x,7] H(

(a) Find the impulse response h[n] of this filter. Is this filter causal?

(b) Suppose that the input of this filter x[n] has a DTFT X(e^jÏ‰) = H(e^jÏ‰), what is the output of the filter y[n].
