MorganStandard Linear & LogicABSTRACTA pplications of the CD4046B Phase-Locked loop device, such as FM demodulation, FSKdemodulation, tone decoding, frequency multiplication, signal conditioning, clocksynchronization, and frequency synthesis, are discussed. The monolithic-formlow-power-consumption CD4046B particularly is desirable for use in portablebattery-powered.
