A TIME-DIVISION ANALOG MULTIPLIER USING AN IMPROVED FULL-WAVE MODULATOR TO MAINTAIN STATIC ACCURACY

摘要

In the field of analog computers there is a need for an electronic analog multiplier which can maintain a high degree of static accuracy for long periods of time. The requirements on bandwidth are low since computer problems are usually time-scaled for display on pen recorders. This paper describes a time-division multiplier that was developed using all solid-state construction. It maintains a static accuracy of 0.1 percent of full-scale output for long periods of time and has a usable bandwidth of 1 kHz.
