A digital-signal-processing-based instrument for phase noise measurement on sinusoidal signals is described. It incorporates a special hardware architecture, which is made up of a core digital signal processor that is connected to a data acquisition board, and takes advantage of a new measurement procedure based on a quadrature demodulation scheme, which has been proposed by the authors. Thanks to...
Measurement of phase noise affecting oscillators or clocks is a fundamental practice whenever the need of a reliable time-base is of primary concern. In spite of the number of methods or techniques either available in literature or implemented as personalities in general purpose equipment, very accurate measurement results can be gained only from expensive, dedicated instruments. To offer a cost-effective...
A digital signal-processing meter for phase noise measurement on sinusoidal signals is dealt with. It enlists special hardware architecture, made up of a core digital signal processor connected to a data acquisition board, and takes advantage of a quadrature demodulation-based measurement scheme, already proposed by the authors. Thanks to an efficient measurement process and an optimised implementation...
