... If we choose the resistors as follows: R1 = Ra = 1 kW, R2 = 2 kW, R3 = 4 kW, R4 = R0 = 8 kW and Rb = 15 kW, then we get the following simple relationship for Vout: Vout = 8V1 + 4V2 + 2V3 + V4 Thus if Vi n represents a binary number (e.g. 1001 = V1 V2 V3 V4 with V1 being the highest order bit) then t ...

Time-to-digital converter
In electronic instrumentation and signal processing, a time to digital converter (abbreviated TDC) 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.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. In some cases interpolating TDCs are also called time counters (TCs).TDCs are used in many different applications, where the time interval between two signal pulses (start and stop pulse) should be determined. Measurement is started and stopped, when either the rising or the falling edge of a signal pulse crosses a set threshold. These requirements are fulfilled 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.
