Pulse amplitude modulation, frequency modulation telemetric data transmitter

Claim 1

A pulse amplitude modulation, frequency modulation telemetric data transmission system comprising: a pulse amplitude modulation telemetry signal subsection having signal conditioners to receive channeled telemetry signals and unify the amplitudes thereof, a commutation rate matrix coupled to said signal conditioners to receive said uniform signals and matrix them to appear on an appropriate number of channel outputs, a channel commutator of gates driven in sequence by a counter circuit that is driven by a clock pulse source with each gate coupled to a channel output of said matrix through said gate to a common output, and a premodulation filter coupled in said common output; a video doppler subsection having a compression amplifier to receive video doppler frequency signals of random amplitude to compress said signals to a uniform amplitude on an output thereof, and a frequency translator coupled to the compression amplifier output to translate said frequency signals to corresponding levels different from the frequency levels of said telemetry signals on an output thereof; a transmitter for transmitting radio frequency signals; a summing amplifier coupled to said common output of said premodulation filter and the output of said frequency translator and having an output coupled to said transmitter to sum said telemetry signals and said video doppler signals into composite signals for transmission; and a power supply subsection having batteries therein coupled through switches and conductors to said telemetry channel, said video doppler channel, said summing amplifier, and said transmitter to switch said conductors to external taps for external power supply under one condition and to switch said conductors to said batteries under another condition whereby telemetry signals of missile operation and video signals of a target object with respect to said missile are transmitted over a single radio channel.
