Abstract

An electrical signal transmission system is disclosed and includes a transmission unit and a receiver unit. The transmission unit converts the relative amplitudes of an input amplitude signal to a time domain representative signal of varying pulse widths, and the receiver unit receives the time domain representative signal and generates an output signal representative of the input amplitude signal.

Claims

1. An electrical signal transmission system comprising:

a transmitter circuit for receiving a television camera output signal and for generating a transmission signal, said transmitter circuit including an impedance matching resistor, an alternating current coupler, a resistor-capacitor network, and a threshold crossing detector for producing said transmission signal wherein said transmission signal represents the transfer function of said television camera output signal; and

a receiver circuit for receiving said transmission signal and for generating an output signal representative of said television camera output signal, said receiver circuit including an impedance matching resistor, and an operational amplifier for generating an output signal that is substantially similar to said television camera output signal, and a radio frequency modulator for input of said output signal to a television set.

2. An electrical signal transmission system comprising;

a transmitter unit for receiving input signals to be transmitted and for television transmission signals to be sent to a receiver, said transmission unit including a circuit which includes a resistor and a capacitor for providing impulse response signals representative of said input signals, and a threshold crossing detector for producing said transmission signals wherein said transmission signals represent the transfer function of said input signals; and

a receiver unit for receiving and outputting said transmission signals that are substantially identical to said input signals, wherein said receiver unit includes an operational amplifier for amplifying said transmission signals for input to suitable receivers, and wherein said television transmission signals are input to a radio frequency modulator for inputting said television transmission signals to a suitable television receiver for reproduction of television pictures.
