Abstract: A phase angle can be measured between an analog signal and a reference signal by converting the analog signal to digital samples in a residue number system (RNS) analog-to-digital converter (ADC), based on a RNS scheme. The phase angle can be measured directly from the RNS values output by the RNS ADC, or the RNS values can be converted to a binary scheme, such as straight binary, offset binary or two's complement, before calculating the phase angle measurement.

Abstract: A method and apparatus for mitigating a phase anomaly in an analogue-to-digital converter (ADC) output signal is disclosed. A plurality of codewords output by the ADC are received and information about an estimated level of interference between an output of the ADC and an input of the ADC due to the codeword is obtained for each codeword based on the logic values of bits in the codeword. In-phase (I) and quadrature (Q) corrections are obtained based on the information about the estimated level of interference, and applied to I and Q values obtained from the ADC output signal.

Abstract: The present invention relates to a pseudo-noise generator comprising a plurality of pseudo-random number generators and an averaging unit. The averaging unit is arranged to receive a plurality of pseudo-random numbers from the plurality of pseudo-random number generators, calculate a mean value of the plurality of pseudo-random numbers, and output said mean value as a digital pseudo-noise signal.
