  2. 555 timer IC - Wikipedia

    en.wikipedia.org/wiki/555_timer_IC

    The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. Derivatives provide two (556) or four (558) timing circuits in one package. [2]

  3. Schmitt trigger - Wikipedia

    en.wikipedia.org/wiki/Schmitt_trigger

    T and − T are the switching thresholds, and M and − M are the output voltage levels. In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. It is an active circuit which converts an analog input signal to a ...

  4. Duty cycle - Wikipedia

    en.wikipedia.org/wiki/Duty_cycle

    Duty cycle. A duty cycle or power cycle is the fraction of one period in which a signal or system is active. [1][2][3] Duty cycle is commonly expressed as a percentage or a ratio. A period is the time it takes for a signal to complete an on-and-off cycle. As a formula, a duty cycle (%) may be expressed as: Equally, a duty cycle (ratio) may be ...

  5. Logic probe - Wikipedia

    en.wikipedia.org/wiki/Logic_probe

    Elenco LP-560 logic probe. It has a red LED for high state, green LED for low state, amber LED for pulsing state, and a changing audible tone. [1] A logic probe is a low-cost hand-held test probe used for analyzing and troubleshooting the logical states (boolean 0 or 1) of a digital circuit. When many signals need to be observed or recorded ...

  6. Pulse-width modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-width_modulation

    t. e. Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an electrical signal.

  8. Crystal oscillator - Wikipedia

    en.wikipedia.org/wiki/Crystal_oscillator

    A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element. [1] [2] [3] The oscillator frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.

  9. Signetics - Wikipedia

    en.wikipedia.org/wiki/Signetics

    Signetics Corporation was an American electronics manufacturer specifically established to make integrated circuits. [1] Founded in 1961, they went on to develop a number of early microprocessors and support chips, as well as the widely used 555 timer chip. The company was bought by Philips in 1975 and incorporated in Philips Semiconductors ...
