Bipolar DAC(digital-to-analog converter) In electronics‚ a digital-to-analog converter (DAC or D-to-A) is a device that converts a digital (usually binary) code to an analog signal (current‚ voltage‚ or electric charge). An analog-to-digital converter (ADC) performs the reverse operation. Signals are easily stored and transmitted in digital form‚ but a DAC is needed for the signal to be recognized by human senses or other non-digital systems. A common use of digital-to-analog converters is generation

not about binary numerals. The main interactive circuit at the top of this page is an arithmetic circuit capable of performing both addition and subtraction on any two 4-bit binary numbers. The circuit has a Mode switch that allows you to choose between adding (M=0) and subtracting (M=1). To understand why this circuit works‚ let’s review binary addition and binary subtraction. We use 4-bit numbers in the examples because the main interactive circuit is a 4-bit adder–subtractor. Binary addition
