What is quantization of filter?

Thus the quantization of filter coefficients creates a deviation in the frequency response of the system. In summary, after quantization, we get a filter that has a frequency response that is different from the frequency response of the filter with unquantized coefficients.

How do you quantize filter coefficients?

After having scaled the coefficients of each SOS, you quantize them by simply rounding them to the closest number on an equidistant grid consisting of 2N numbers, where N is the number of bits.

How do you quantize digital signals?

The simplest way to quantize a signal is to choose the digital amplitude value closest to the original analog amplitude.

What happens to the signal in quantizing?

The digitization of analog signals involves the rounding off of the values which are approximately equal to the analog values. The method of sampling chooses a few points on the analog signal and then these points are joined to round off the value to a near stabilized value. Such a process is called as Quantization.
