Abstract: An interpolation filter for interpolating a digital signal includes a cascade of template filters, each having an identical template transfer function A(z), which is arranged to receive and filter an input sequence representing the digital signal sampled at an input sampling rate. Ancillary circuitry is coupled to the cascade so as to produce first and second phase outputs. A multiplexer is arranged to multiplex the phase outputs in order to generate an output sequence having an output sampling rate equal to twice the input sampling rate.

Abstract: A method for calculating the mask for an arbitrary delay of a pseudo-noise sequence uses only XOR operations on previously calculated masks. A method for calculating the mask for an arbitrary delay of a pseudo-noise sequence whose shift register polynomial is of order R uses no more than NOP operations where NOP is independent of the delay and NOP is on the order of R.
