This program develops an advanced methodology to aid the design, test and evaluation of receiver systems. Computer programs were developed for treating receiver performance degradations due to noise, nonlinearities, linear distortion, and signal interference. Specifically, two computer programs were generated for treating receiver processes encountered in signal paths and synthesizers respectively. Signal path computations are made relative to the receiver frequency plan, receiver noise figure and sensitivity performance, second and third order receiver intermodulation intercepts, permissible two sinusoid signal levels and dynamic range performance. Spurious response performance is computed for each spur product type generated at each mixer, yielding the worst case spur frequency and spur signal level at the receiver input and the corresponding worst case set of mixer local oscillator frequencies. Computations are also made of the receiver output waveform response to an essentially arbitrary input signal waveform. Synthesizer program computations are made of the frequency plan, worst case phase modulation of each synthesizer output by spurious products generated at each phase comparator and mixer and worst case phase modulation of each synthesizer output by noise generated on each VCO and in the phase locked loop circuits.
