Abstract: A wrist band for a wrist-mounted radio system is provided wherein a metallic wrist-band buckle need not be insulated. The system includes a radio receiver which includes a differential input in a wrist-band antenna with a "null point" at the location of the buckle. The wrist-band antenna is insulated from the wearer's body at all points except at the buckle.

Abstract: A frequency synthesizer apparatus is disclosed which combines a digital multiplier in the count down and phase comparison section with an oscillator entirely contained on an integrated circuit. Inclusion of the digital multiplier allows simultaneous realization of high loop bandwidth and fast tuning speed. The large loop bandwidth facilitates use of a totally integrated oscillator, which was heretofore not useable because of inferior phase noise characteristics. An integrated filter further enhances loop bandwidth while maintaining stability. Synchronizing the modulus switching of a multi-modulus prescaler with the multiplier coefficient minimizes spurious responses in the synthesized output.

Abstract: A digital receiver samples data from an amplitude modulated subcarrier at a rate less than twice the subcarrier's maximum frequency by sampling at known phase points. Sampling at known phase points is achieved by generating a sampling clock from a signal phase locked to and transmitted with the modulated data subcarrier.
