Abstract
The invention is a sample rate converter, which converts input sample values of a signal digitized with a first predetermined clock frequency into desired sample values at a second virtual sample frequency, with a delay device, which delays the serial input sample values and outputs in parallel a block of delayed input sample values z.sup.-2 to z.sup.+2, a computing device, with a WHT stage, which transforms the delayed input sample values (z.sup.-2 to z.sup.+2), by using a Walsh-Hadamard transformation, into the WHT domain, and an interpolating device, which interpolates in equally weighted manner the resulting WHT coefficients and performs an amplitude correction of the interpolation results.
