The most notable application of EHW

The most notable application of EHW so far is in the design of analogue circuits. While digital devices have become ubiquitous, they still have to communicate with the real world—and the real world remains stubbornly analogue. The fact is that people do not talk, hear, see, touch and taste in the ones and zeros of digital computerspeak. Analogue circuits are needed to measure or produce the wave-like signals of light, sound or temperature. Other analogue circuits known as A-D and D-A converters are needed to translate these continuous wave-like signals to and from the discrete language used by digital devices. Analogue circuitry is thus an essential part of the sensors, receivers and display units that play such a vital role in the modern wireless world.
