  2. Frequency divider - Wikipedia

    en.wikipedia.org/wiki/Frequency_divider

    Frequency divider. A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, , and generates an output signal of a frequency: where is an integer. Phase-locked loop frequency synthesizers make use of frequency dividers to generate a frequency that is a multiple of a ...

  3. Asynchronous module definition - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_Module_Definition

    Asynchronous module definition ( AMD) is a specification for the programming language JavaScript. It defines an application programming interface (API) that defines code modules and their dependencies, and loads them asynchronously if desired. Implementations of AMD provide the following benefits:

  4. Modulation - Wikipedia

    en.wikipedia.org/wiki/Modulation

    In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. [1] For example, the modulation signal might be an audio signal representing sound from a ...

  5. 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 ...

  6. Counter (digital) - Wikipedia

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

    An electronic counter is a sequential logic circuit that has a clock input signal and a group of output signals that represent an integer "counts" value. Upon each qualified clock edge, the circuit will increment (or decrement, depending on circuit design) the counts. When the counts have reached the end of the counting sequence (maximum counts ...

  7. Asynchronous circuit - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_circuit

    Asynchronous circuit ( clockless or self-timed circuit) [1] : Lecture 12 [note 1] [2] : 157–186 is a sequential digital logic circuit that does not use a global clock circuit or signal generator to synchronize its components. [1] [3] : 3–5 Instead, the components are driven by a handshaking circuit which indicates a completion of a set of ...

  8. Static random-access memory - Wikipedia

    en.wikipedia.org/wiki/Static_random-access_memory

    Historical. v. t. e. Static random-access memory ( static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The term static differentiates SRAM from DRAM ( dynamic random-access memory): SRAM will hold its data permanently ...

  9. Modular arithmetic - Wikipedia

    en.wikipedia.org/wiki/Modular_arithmetic

    Adding 4 hours to 9 o'clock gives 1 o'clock, since 13 is congruent to 1 modulo 12. In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones ...
