In this post we implement wiht VHDL a cascaded second order filter in fixed point which reuses a single DSP block for all of the multiplications.

In this post we design and implement a 6th order Chebyshev filter using fixed point and use it with Efinix Titanium to demodulate a sigma delta bit stream.

The next most important operation after summation, subtraction and multiplication is the fourth fundamental operation, division. As the inverse operation for multiplication, division is used for calculating scaling gains for measurements and controls. It is also needed for calculating further mathematic functions, for example arctangents are readily calculated using rational approximations which require evaluation of division

Control algorithms as well as measurements use signal processing to filter out unwanted noise from the analog to digital converter results and control outputs. Function approximations
