I have a signal with a sample rate of 8.9286 MHz and I want to downsample it to 500 kHz. Since 8.9286 is not an integer multiple of 0.5 I can't simply decimate. WebThe process of reducing the sampling rate by an integer factor is referred to as downsampling of a data sequence. We also refer downsampling as “decimation” (not taking one of ten). The term “decimation” used for the downsampling process has been accepted and used in many textbooks and fields. diary things
