Abstract: An electronic computer controls the operation of a communication system such as a citizen band (CB) radio. An electronic computer includes a program memory which stores the control sequence and code for an electronic lock. The computer also includes a data memory for storing command and data signals from a keyboard through a set of input/output registers and intermediate results from computer computations. Other elements of the computer may be a timer, an accumulator and logic unit (ALU) and set of working registers. A digital to analog converter converts an appropriate binary output from the computer into a voltage which is used as a reference for the communication system power supply providing control for this device. A second binary output from the computer provides for the control of the frequency signal channel over which the communications system is to transmit.
