ABSTRACT
Multipliers are classified into: time division multipliers, peak responding multipliers, and pulse position responding multipliers. Peak responding multipliers are further classified into peak detecting multipliers and peak sampling multipliers. Types of peak responding multipliers are double single slope, double dual slope, and pulse width integrated multipliers. If the width of a pulse train is made proportional to one voltage and the amplitude of the same pulse train to a second voltage, then the average value of this pulse train is proportional to the product of two voltages and is called “time division multiplier,” “pulse averaging multiplier,” or “sigma delta multiplier.” In general, multipliers can be implemented with analog multiplexers and analog switches.
