For example, … Webpass-band and the stop-band characteristic of the CIC filter at an expense of the increased complexity [15]. Since all of the coefficients of these FIR filters are unity, and therefore symmetric, a CIC filter also has a linear phase response and constant group delay [16]. The magnitude response at the output of the filter can be shown to be: R f dhl class 2
