TDC

In electronic instrumentation and signal processing, a time-to-digital converter (TDC) or time digitizer (TD) is a device for recognizing events and providing a digital representation of the time they occurred. For example, a TDC might output the time of arrival for each incoming pulse. Some applications wish to measure the time interval between two events rather than some notion of an absolute time, and the digitizer is then used to measure a time interval and convert it into digital (binary) output. In some cases, an interpolating TDC is also called a time counter (TC).
