An analog signal to discrete time interval converter (ASDTIC) is a specialized kind of an analog-to-digital converter, which converts the analog input signal (e.g. voltage or current) to time intervals between pulses. This conversion is a type of Pulse-width modulation (PWM). The origin of the term ASDTIC lies with NASA around 1970. [1]
MIDI beat clock, or simply MIDI clock, is a clock signal that is broadcast via MIDI to ensure that several MIDI-enabled devices such as a synthesizer or music sequencer stay in synchronization. Clock events are sent at a rate of 24 pulses per quarter note .
In the n th clock cycle, if voltage is higher than digital equivalent voltage of the number in register, the (n+1) th digit from the left is set to 1. If the voltage were lower than digital equivalent voltage, then n th digit from left is set to zero and the next digit is set to 1. To perform a conversion, an N-bit ADC requires N such clock ...
Telechron electric alarm clock. Telechron alarm clocks are particularly popular with collectors. Until about 1940, the overwhelming majority of Telechron alarm clocks had bell alarms. The entire mechanism was enclosed in a bell housing of steel. Atop the clock's coil was a metal strip that vibrated at 60 cycles per second when the alarm was ...
Founded as the Utility Manufacturing Company in 1934, it produced a wide variety of products, including wall clocks, alarm clocks, electric shavers, analog cameras, and more. It sold these through a medley of brands—including Falcon, Spartus, Galter, Regal, Monarch, Spencer, among others. It was founded in 1934 by Jack Galter (1904–1993) as ...
Inter-range instrumentation group timecodes, commonly known as IRIG timecode, are standard formats for transferring timing information.Atomic frequency standards and GPS receivers designed for precision timing are often equipped with an IRIG output.
Accurist became the first company to sponsor the United Kingdom's speaking clock service between 1986 and 2008, [1] and also sponsored a Millennium Countdown clock at the Royal Observatory, Greenwich, which counted down the last 1,000 days before the year 2000 at the historic observatory.
Digital clocks typically use the 50 or 60 hertz oscillation of AC power or a 32,768 hertz crystal oscillator as in a quartz clock to keep time. Most digital clocks display the hour of the day in 24-hour format; in the United States and a few other countries, a commonly used hour sequence option is 12-hour format (with some indication of AM or PM).
