We are demonstrating a simple first order filter. Comparing to FIR (Finite Impulse Response) filters: IIR filter requires less number of orders for same specifications.
y(n) = k1*y(n-1) + p1*x(n) is the output signal in this current moment.
Take a note that the simulation is done in vector waveform file and that we changed in the properties of the input data from ASCII to UNSIGNED DECIMAL! After we set the values as we want, the simulation starts.

It is good to notice that the output changes only when a rising edge of the clock is present.

The same filter is made in MATLAB as a proof that or simulation is valid. The difference between the output signals of these softwares is less than 10% which is enough.

Thanks for watching!
