The SI unit for the period, as for all measurements of time, is the second. [5] A traditional unit of frequency used with rotating mechanical devices, where it is termed rotational frequency, is revolution per minute, abbreviated r/min or rpm. [6] Sixty rpm is equivalent to one hertz. [7]
Quantity Unit Remarks Name Symbol Definition Name Symbol period, periodic time: T: time of one cycle: second: s: frequency: f, ν: f = 1/T: hertz: Hz: 1 Hz = 1 s −1: loudness level: L N: L N = ln(p eff /p 0) 1 kHz where p eff is the root-mean-square value of the sound pressure of a pure tone of 1 kHz, which is judged by a normal observer under standardized listening conditions as being as ...
Used in radio receivers; mixes with 10.7 MHz intermediate frequency (IF) yielding 455 kHz signal, a common second IF for FM radio [15] 10.368 DECT: 14400 Reference clock for DECT phones. Available as TCXO. Other frequencies are 13.824 and 20.736 MHz. UART clock allows integer division to common baud rates up to 14,400(×16×45) or 28,800(×8×45)
The first fully mechanical digital computer, the Z1, operated at 1 Hz (cycle per second) clock frequency and the first electromechanical general purpose computer, the Z3, operated at a frequency of about 5–10 Hz. The first electronic general purpose computer, the ENIAC, used a 100 kHz clock in its cycling unit. As each instruction took 20 ...
The cycle per second is a once-common English name for the unit of frequency now known as the hertz (Hz). Cycles per second may be denoted by c.p.s., c/s, or, ambiguously, just "cycles" (Cyc., Cy., C, or c). The term comes from repetitive phenomena such as sound waves having a frequency measurable as a number of oscillations, or cycles, per ...
