Even in a Digital World, Analog Multipliers are Still Relevant

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...

Speeding up the CORDIC algorithm with a DSP

Digital signal processors (DSPs) crunch the numbers for applications that require fast analog-to-digital-to-analog conversion, such as software-defined radio and radar. If you weren't using a DSP, you ...
