  2. Timer - Wikipedia

    en.wikipedia.org/wiki/Timer

    A typical kitchen timer. A timer or countdown timer is a type of clock that starts from a specified time duration and stops upon reaching 00:00. An example of a simple timer is an hourglass. Commonly, a timer triggers an alarm when it ends. A timer can be implemented through hardware or software.

  3. Counter (digital) - Wikipedia

    en.wikipedia.org/wiki/Counter_(digital)

    Ripple counters exhibit unstable output states while the input clock propagates through the circuit. The duration of this instability (the output settling time) is proportional to the number of flip-flops. This makes ripple counters unsuitable for use in synchronous circuits that require the counter to have a fast output settling time. Also, it ...

  5. Time-to-digital converter - Wikipedia

    en.wikipedia.org/wiki/Time-to-digital_converter

    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 [1] interpolating TDCs are also called time counters (TCs). TDCs are used to determine the time interval between two signal pulses (known as start and stop pulse).

  6. Frequency counter - Wikipedia

    en.wikipedia.org/wiki/Frequency_counter

    Most frequency counters work by using a counter, which accumulates the number of events occurring within a specific period of time.After a preset period known as the gate time (1 second, for example), the value in the counter is transferred to a display, and the counter is reset to zero.

    The difference between ICHRAs and QSEHRAs is who they cover. While they offer similar coverage, QSEHRAs can only be offered by small businesses with fewer than 50 full-time employees. Companies of ...

  8. CPU time - Wikipedia

    en.wikipedia.org/wiki/CPU_time

    When a program wants to time its own operation, it can use a function like the POSIX clock() function, which returns the CPU time used by the program. POSIX allows this clock to start at an arbitrary value, so to measure elapsed time, a program calls clock(), does some work, then calls clock() again. [1] The difference is the time needed to do ...
