Time Interpolation Implementation
The counter implementation's accuracy is limited by the clock frequency. If time is measured by whole counts, then the resolution is limited to the clock period. For example, a 10 MHz clock has a resolution of 100 ns. To get resolution finer than a clock period, there are time interpolation circuits. These circuits measure the fraction of a clock period: that is, the time between a clock event and the event being measured. The interpolation circuits often require a significant amount of time to perform their function; consequently, the TDC needs a quiet interval before the next measurement.

Famous quotes containing the word time:
“Most women without children spend much more time than men on housework; with children, they devote more time to both housework and child care. Just as there is a wage gap between men and women in the workplace, there is a “leisure gap” between them at home. Most women work one shift at the office or factory and a “second shift” at home.”
—Arlie Hochschild (20th century)
