Sample Rate Conversion of Arbitrary Non-integer Factors

Abstract: The farrow structure allows for flexible filtering, adjustable fractional delay filters, and SRC (Sample Rate Conversion) by arbitrary non-integer factors. It has been noted in recent publications that it is suitable for band passing SRC. When passband centres are placed above the input sampling rate, the complexity of the interpolator becomes approximately proportional to the centre frequency. We propose a novel construct, the modified Farrow structure, which allows for arbitrary high centre frequencies without increasing the prototype Farrow filter’s Polynomial degree. Modulated functions are constructedas low-order polynomials to avoid the expensive generation of trigonometric functions.
Keywords: Digital Filters, Farrow Structure, Decimators, Interpolators, Band-Pass Filtering Sample Rate Conversion of Arbitrary Non-integer Factors
