Four-sample sample-rate converter

摘要: A transcoding arrangement transcodes television signals sampled at a first clock rate into second rate. An integer number of samples the are assembled blocks, each block containing an signal. The integers selected to reduce multipliers required perform transcoding. delay element forms four successive delayed incoming and last summed then multiplied by running variable multiplicand form weighted sum third respective multiplicands samples. which is subtracted from signal interpolated output sample. related effective position sample being formed within
