  2. Function generator - Wikipedia

    en.wikipedia.org/wiki/Function_generator

    A completely different approach to function generation is to use software instructions to generate a waveform, with provision for output. For example, a general-purpose digital computer can be used to generate the waveform; if frequency range and amplitude are acceptable, the sound card fitted to most computers can be used to output the generated wave.

  3. Signal generator - Wikipedia

    en.wikipedia.org/wiki/Signal_generator

    A signal generator may be as simple as an oscillator with calibrated frequency and amplitude. More general-purpose signal generators allow control of all the characteristics of a signal. Modern general-purpose signal generators will have a microprocessor control and may also permit control from a personal computer.

  4. Time base generator - Wikipedia

    en.wikipedia.org/wiki/Time_base_generator

    A time base generator (also timebase or time base) is a special type of function generator, an electronic circuit that generates a varying voltage to produce a particular waveform. Time base generators produce very high frequency sawtooth waves specifically designed to deflect the beam of a cathode ray tube (CRT) smoothly across the face of the ...

    The General Purpose Interface Bus is an IEEE-488 (a standard created by the Institute of Electrical and Electronics Engineers) standard parallel interface used for attaching sensors and programmable instruments to a computer. GPIB is a digital 8-bit parallel communications interface capable of achieving data transfers of more than 8 Mbytes/s.

  6. Programmable logic array - Wikipedia

    en.wikipedia.org/wiki/Programmable_logic_array

    PLA schematic example. A programmable logic array (PLA) is a kind of programmable logic device used to implement combinational logic circuits.The PLA has a set of programmable AND gate planes, which link to a set of programmable OR gate planes, which can then be conditionally complemented to produce an output.

  7. 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 or four timing circuits in one package. [2]

  8. Voltage-controlled oscillator - Wikipedia

    en.wikipedia.org/wiki/Voltage-controlled_oscillator

    For low-frequency VCOs, other methods of varying the frequency (such as altering the charging rate of a capacitor by means of a voltage-controlled current source) are used (see function generator). The frequency of a ring oscillator is controlled by varying either the supply voltage, the current available to each inverter stage, or the ...

  9. Pulse generator - Wikipedia

    en.wikipedia.org/wiki/Pulse_generator

    A pulse generator is either an electronic circuit or a piece of electronic test equipment used to generate rectangular pulses. Pulse generators are used primarily for working with digital circuits ; related function generators are used primarily for analog circuits .
