cavity resonator वाक्य

Activities included design, construction, and demonstration of voice-modulation equipment for a 10 cm magnetron ( July 1943 ), a microwave triode oscillator at 25 cm using cylindrical cavity resonators, equipment designed for microwave radar in field use ( wavemeter, echo box, thermistor power meter, etc . ) and microwave measurement technique.
Cavities in the form of jars built into the inner surface of a dome may serve to compensate for this interference by diffusing sound in all directions, eliminating echoes while creating a " divine effect in the atmosphere of worship . " This technique was written about by Vitruvius in his cavity resonators determine the effect they have : reinforcing certain frequencies or absorbing them.
After the war he did not return to the communist People's Republic of Poland and stayed in the USA . He helped in the development of VHF cavity resonators that allowed adjacent channel operation, was a key designer for the Motorola Sensicon receiver which used a selective filter in front of the IF amplifier, and created microwave relay equipment for use in transmitting multi-channel telephone, data and TV . In Motorola's Government Electronics Division he developed the SSB Radio Central Concept AN / USC-3, Motorola s RADEM system ( RADAS ), the Deltaplex I digital troposcatter system and lightweight tropo equipment AN / TRC-105.
