Digital low pass filter |
摘要 |
A digital low pass filter of the FIR type stores the input signal into register means with a plurality of taps. These taps are connected to address a look up table and the filtered output signal is derived from the output of the look up table. The filter may e.g. be used in systems where a one-bit direct stream digital (DSD) signal has to be requantized.
