摘要:
The sending and receiving of voice-frequency signals over telephone circuits is well established as a practice with thermionic-valve receivers. Transistor receivers would reduce the steady drain on the exchange power supply. Capital cost and reliability in service have yet to be determined.The paper outlines the technical requirement of v.f. receivers, compares the design features of valves and transistors, and uses an experimental design of transistor receiver to illustrate the problems involved.
