Information transmission system level control - has piloto receiver and pulse regeneration through intermediate amplifiers

摘要

The information system level control has a number of intermediate amplifiers each of which comprises a semi-conductor amplifier, capacitors and inductors forming a low pass filter parallel with a storage unit. The most remote amplifier incorporates a pilot filter and controller, with pulse generators and a comparison circuit. Intermediate amplifiers also embody pulse generators but have pulse shaping circuits decoupled in the incoming signal direction and coupled in the outgoing signal direction. Outgoing signals of the pulse generators heat a thermistor in the circuit of the semiconductor amplifier.
