Analog Multipliers – Part II
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, which is called time division multiplier or pulse averaging multiplier or sigma–delta multiplier. The time division multiplier can be implemented using (1) triangular wave (2) sawtooth wave and (3) without using any reference wave.
There are 2 types of time division multipliers (TDM) (i) multiplexing TDM (MTDM) and (ii) switching TDM (STDM). A time division multiplier using analog 2 to 1 multiplexer is called multiplexing TDM. A time division multiplier using analogue switches is called ...
