What is the meaning of transition frequency? 2. most of the time the transistor operating frequency is a fraction of the ft. (like 1/5) 3. this is just a characteristic of the die. Bond wires introduce parasitics that lower the actual ft. So ft is just a so called figure of merit to compare different transistors.

Time to live Time to live. For the 1969 French film, see Time to Live (film). Time to live (TTL) or hop limit is a mechanism that limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded.

Voice frequency Fundamental frequency The voiced speech of a typical adult male will have a fundamental frequency from 85 to 180 Hz, and that of a typical adult female from 165 to 255 Hz. Thus, the fundamental frequency of most speech falls below the bottom of the voice frequency band as defined above.

- The fundamental frequency, often referred to simply as the fundamental, is defined as the lowest frequency of a periodic waveform. In terms of a superposition of sinusoids, the fundamental frequency is the lowest frequency sinusoidal in the sum.

radio frequency Definition of radio frequency. : any of the electromagnetic wave frequencies that lie in the range extending from below 3 kilohertz to about 300 gigahertz and that include the frequencies used for communications signals (as for radio and television broadcasting and cell-phone and satellite transmissions) or radar signals.

frequency Electromagnetic frequencies, formerly expressed in cycles per second (cps), are now expressed in hertz (Hz). The number of cycles or repetitions of a periodic wave or signal per unit time. In electromagnetic radiation, frequency is usually expressed in units of hertz (Hz), where 1 Hz = 1 cycle per second.

Nyquist frequency Thus, Nyquist rate is a property of a continuous-time signal, whereas Nyquist frequency is a property of a discrete-time system. When the function domain is time, sample rates are usually expressed in samples/second, and the unit of Nyquist frequency is cycles/second (hertz).

TTL - transistor-transistor logic, Time to Live or through-the-lens (1) Short for transistor-transistor logic, a common type of digital circuit in which the output is derived from two transistors. The first semiconductors using TTL were developed by Texas Instruments in 1965. The term is commonly used to describe any system based on digital circuitry, as in TTL monitor.

- The propagation delay of a signal in the internal loop from the driver. input to the receiver output is typically used as a qualitative measure of a CAN transceiver. This. propagation delay is referred to as the loop time (tLOOP in a TI data sheet), but takes on varied. nomenclature from vendor to vendor.

Frequency For cyclical processes, such as rotation, oscillations, or waves, frequency is defined as a number of cycles per unit time. In physics and engineering disciplines, such as optics, acoustics, and radio, frequency is usually denoted by a Latin letter f or by the Greek letter or ν (nu) (see e.g. Planck's formula).

- Shares & Saves. Save. Through-the-lens metering, also known as TTL, is a method of measuring light for photographic exposure purposes. In TTL metering, the light is measured using an in-camera light meter, eliminating the need to use a separate, hand-held light meter.he advantage of using a through-the-lens flash metering system is that the photographer is not required to perform the calculation of flash output, which eliminates a margin of error.

Linear temporal logic From Wikipedia, the free encyclopedia. In logic, linear temporal logic or linear-time temporal logic (LTL) is a modal temporal logic with modalities referring to time. In LTL, one can encode formulae about the future of paths, e.g., a condition will eventually be true, a condition will be true until another fact becomes true, etc.

- Frequency: The number of cycles, repetitions, or oscillations of a periodic process completed during a unit of time. The frequency of waves in the electromagnetic spectrum (radio waves) is designated in hertz (Hz), kilohertz (kHz or 1000 Hz). One hertz is equivalent to one cycle per second. Frequency band: A continuous range of frequencies extending between two limiting frequencies. Frequency bands that are involved in two-way radio are 25-50 MHz (VHF-low band), 150-174 MHz (VHF-high band), 450-512 and 890-960 MHz (UHF band).

Definitions &Translations Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
