A low-pass filtering step must … ph meter toshconIn digital signal processing, a cascaded integrator–comb (CIC) is an optimized class of finite impulse response (FIR) filter combined with an interpolator or decimator. A CIC filter consists of one or more integrator and comb filter pairs. In the case of a decimating CIC, the input signal is fed through one or more cascaded integrators, then a down-sampler, followed by one or more comb sections (equal in number to the number of integrators). An interpolating … ph meter vs indicatorWebGenerally, CIC filters with some orders are cascaded (multistage) to achieve the desired sampling rate and required noise level.
