Unfortunately this week I was unable to make as much progress as I would have liked. This week I started to create the SystemVerilog Filter and MATLAB filter files for the simulator. The filter we have chosen is a second order infinite impulse response filter.
A second-order infinite impulse response (IIR) filter is a discrete-time filter defined by a difference equation that uses both past inputs and past outputs, allowing it to achieve complex frequency responses with only a few coefficients. It is the lowest-order filter capable of producing resonance, making it especially useful for shaping audio signals in digital synthesizers. It is computationally efficient and well-suited for real-time and hardware implementations, while still providing flexibility through tunable parameters such as cutoff frequency and Q factor.
Next week, I will use waveform analysis to verify the SystemVerilog implementation, integrate the filter with the other system modules, and connect the MATLAB code into the overall simulation pipeline
