DARPA’s ultrahigh speed Analog-to-Digital converter (ADC) to improve performance of Radar, Electronic Warfare and Communications

Our society is highly connected through various digital services. However, much of the information we exchange and process is of an analogue nature in its origin. Analogue-to-digital conversion is thus already an integral part of our modern digital society. Digital signal processing is a powerful technique for storing, analysing and manipulating digital signals. Ultimately, the quality of the signal to be processed is determined by the performance of the analogue-to-digital converter (ADC) which is used to sample the original analogue signal in the first place and produce a digital representation of it, writes Dr Chin.
