Universal (FIR and IIR) comb filter with a single delay. See unidelayDemo for examples of effects possible with this very versatile unit. Inputs: x = input signal. BL = blend control for feedforward of input sample [0,1] FB = gain for feedback (iir) [0,1] FF = gain for feedforward (fir) [0,1] dly = length of delay in seconds

The feedforward portion of the CIC filter is called the comb section, whose differential delay is D, while the feedback section is typically called an integrator. The comb stage subtracts a delayed input sample from the current input sample, and the integrator is simply an accumulator. The CIC filter's difference equation is: Equation 6
The recursive comb filters or Cascaded Integrator Comb filter (CIC) are commonly used as decimators for the sigma delta modulators. This paper presents the VLSI implementation, analysis and design of high speed CIC filters which are based on a low-pass filter. These filters are used in the signal decimation which has the
Cascaded Integrator comb (CIC) decimation filter is useful to reduce the data sampling rate such high bandwidth applications The implementation of decimator & interpolator using MATLAB as standard FIR and cascaded integrator comb filter by using the multistage design techniques.
This filter class can operate at high frequencies and is suitable for a single-chip VLSI implementation. The main applications are in communication systems such as software radio and satellite communications. 1-COMB-BASED FILTER (Cascaded Integrator Comb (CIC) Filter) The CIC filter is a combination of digital integrator and

• The feedforward comb filter models the superposition of a ``direct signal'' plus an attenuated, delayed signal , where the attenuation (by ) is due to ``air absorption'' and/or spherical spreading losses, and the delay is due to acoustic propagation over the distance meters, where is the sampling period in seconds, and is sound speed.
• The script makes a 440 Hz sinusoid and adds 50 Hz harmonic noise. A 50 Hz comb filter is created using a fractional delay filter. THe signal is then filtered with the filter and the output is played as a sound before and after the filtering process. For more detail try looking here

• Description fdesign.comb specifies a peaking or notching comb filter. Comb filters amplify or attenuate a set of harmonically related frequencies. d=fdesign.comb creates a notching comb filter specification object and applies default values for the filter order (N=10) and quality factor (Q=16).

• Nov 09, 2009 · As mentioned above, aliasing occurs if the OCT signal is outside the principal measurement range set by the frequency comb filter FFP-FC. The same aliasing phenomenon was also reported by Jung et al. using a light source with an external frequency comb filter . Figure 10(a) shows the PSF when reflection is at 0.06mm depth.
