A low power frequency synthesiser circuit (30) for a radio transceiver, the synthesiser circuit comprising: a digital controlled oscillator configured to generate an output signal having a frequency controlled by an input digital control word (DCW); a feedback loop connected between an output and an input of the digital controlled oscillator, the ...

Frequency Frequency-Rate Spectral Analysis
1987Target and/or sensor motion can smear a received acoustic tonal over many frequency cells when the frequency resolution is matched to the “at rest” tonal frequency width. In addition to a loss of frequency resolution there is a degradation in SNR. The FFR (Frequency Frequency- Rate spectral analysis) within limits eliminates the smearing of acoustic ...
