What Is Input Quantization Error? |
|
Answer» The filter coefficients are computed to infinite precision in THEORY. But in DIGITAL computation the filter coefficients are represented in binary and are stored in registers. If a b bit register is used the filter coefficients must be rounded or TRUNCATED to b bits ,which PRODUCES an error. The filter coefficients are computed to infinite precision in theory.
