WebJan 13, 2016 · So, H ( z) = 1 + exp ( − 2 j ω) at z = exp ( j ω). When ω = 0; H ( z) = 2 and w = π gives H ( z) = 2. Thus, both at high and low frequencies the the system function provides same gain and hence the filter with the given H ( z) is a BAND REJECT/ NOTCH FILTER with H ( z) = 0 at ω = π / 2.
