Farrow Structure - Sampling Clock Offset Estimation
WebJun 16, 2015 · Farrow structure is an efficient way to realize tunable filter characteristics such as variable fractional delay , , , sampling rate conversion (SRC) , and variable cut-off frequencies . In a variable fractional delay filter, all the input samples are delayed by a factor, whereas in SRC, every input sample is delayed by varying factors. WebNow we can present the final structure of the third-order Farrow filter. This structure is shown in Figure 6. Figure 6: Third-order Farrow Filter. Filters for calculating polynomial coefficients based on signal samples are represented by different colors: - black - red - blue - green. Gray marked branches multiplied by zero, which can be ...
