Spurious Product Zone Chart a Practical Approach to Frequency Conversion Synthesis

Mixer charts and computerized spurious product search are commonly utilized techniques for determining the spurious/intermodulation spectrum of communication systems or equipment utilizing frequency conversion. Both methods require intuition, a trial-and-error approach, and lack the adaptability to illustrate computer graphics. The spurious product zone charting method provides a clear, quick, and concise mathematical/ graphical presentation of spurious/intermodulation (IM) products resulting from conversion processes. It adapts easily to computer aided design graphic displays or to small calculators with alphanumeric readouts.
