Abstract:
A system for generating a waveform represented by one of the following equations: ##EQU34##wherein .theta. is the angle in radians of the waveform; T is an integer from 1 to .infin. representing the truncation point of the formula; and R(.theta.) represents an amplitude of the waveform, the system comprising:an oscillator that receives an input and generates a binary coded decimal output;a binary counter that receives the binary coded decimal output and generates a binary signal;an EPROM that receives the binary signal at an address and generates an output corresponding to a number contained at the address;a digital-to-analog converter that converts the number into a voltage value; anda signaling power supply that receives the voltage value and generates the waveform.
