TDCs are used to timestamp events and measure time differences between events, especially where picosecond precision and high accuracy is required, such as the measurement of events in high energy physics experiments, where particles (e.g. This pattern is seen in many physical experiments, like time-of-flight and lifetime measurements in atomic and high energy physics, experiments that involve laser ranging and electronic research involving the testing of integrated circuits and high-speed data transfer. Measurement is started and stopped when the rising or falling edge of a signal pulse crosses a set threshold. ![]() TDCs are used to determine the time interval between two signal pulses (known as start and stop pulse). In some cases interpolating TDCs are also called time counters (TCs). In electronics time-to-digital converters (TDCs) or time digitizers are devices commonly used to measure a time interval and convert it into digital (binary) output. Some applications wish to measure the time interval between two events rather than some notion of an absolute time. For example, a TDC might output the time of arrival for each incoming pulse. In electronic instrumentation and signal processing, a time-to-digital converter ( TDC) is a device for recognizing events and providing a digital representation of the time they occurred.
