Analog signal magnitude can convert to digital and then reconvert for display {compression-decompression} {code-decoder} {codec}, possibly using time-division multiplexing.
Sampling analog signal magnitude at regular intervals can code binary signals {pulse-code modulation} {analog-to-digital}, possibly using multiplexing {time-division multiplexing}.
Digital input can go through low-pass filter with frequency close to digital frequency {pulse-width modulation} {digital-to-analog}. Negative feedback in one-bit digital-to-analog converters {Digital to Analog Converter} (DAC) can create high-pass filter that eliminates noise {pulse-density modulation} {oversampling DAC}. Digital bits can have resistances across voltage or have current sources {binary weighted DAC} {R2R ladder DAC} {segmented DAC} {hybrid DAC}.
