Abstract: Systems and method for resampling are provided. A method of resampling includes receiving a first sampled signal that is sampled at a first sample rate, where the first sample rate is a submultiple of a system clock rate for a Farrow filter. The method further includes resampling the first sampled signal, using the Farrow filter having a plurality of finite impulse response (FIR) filters and an arbitrary position interpolator, at a second sample rate to generate a second sampled signal. The interpolation factor for each sample of the second sampled signal is retrieved from at least one lookup table stored in memory and the first sample rate and the second sample rate are fixed and locked to a common frequency reference. The method further includes outputting the second sampled signal at the second sample rate.
