Abstract : A programmable phase-locked loop frequency synthesizer for a multi-channel sonobuoy transmitter is disclosed. The phase-locked loop, including a counter/dividr utilizing variable modulus prescaling techniques, is modulated at its voltage-controlled oscillator (VCO) by an external signal which is preemphasized by a compensation network in order to correct for the roll-off characteristic response of the loop below its natural frequency.
