4：Do you really know about electronic component?(3)

21.operational amplifier

Operational amplifier is a high magnification circuit unit. In the actual circuit, often be combined with feedback network composed a function module.

22.voltage follower

Voltage follower is that output voltage and the input is the same. The amplificatory multiple always less than and be closed to 1. The prominence of voltage follower is that high impedance input and low output.?

23.waveform generator

Signal generator that digital frequency modulation and amplitude modulation.?

24.logic gate?

Logic gate circuit is used to achieve basic and common logic operation. Be called gate circuit for short. Basic circuit include and gate, or gate and not gate (inverter).

And gate A hardware device that computes the AND of two or more inputs. Only all inputs are“1”, the result is“1”; or the result is“0”.

Or gate A logic device that computes the OR of two or more inputs. One input is “1”, the result is“1”.?

Not gate A logic circuit that computes the NOT of the input. Also called an inverter.The result is the opposition with the input.

25.combination of logic

The characteristic of combination of logic at function is that output at any time only depends on input of the time; it’s not related to the state of the original circuit.

26.data selector

In the multi-channel data transmission, choosing anyone circuit according to need, called data selector, also called multi-channel selector or multi-channel switcher.?

27.data distributor

Send one input data to anyone of m output ports, called data distributor, also called multi-channel distributor; its logic function is exactly opposition to the data selector.

28.encoder/decoder

It is oppositional process of encoding and decoding. General encoder is converted to decimal code corresponding to other code. Each code represents a definite signal or object when encoding. Decoding is a process of translating the certain meanings of the code state; the circuit achieves to decode is decoder. In the other words, decoder is the circuit that translates the state of input binary code into output signals so that express the original meaning circuit.

29.IC integrated circuit

A semiconductor that includes a complete circuit, mostly made up of transistor and resistors. Abbreviated IC.?

30.latch?

To capture the logical state of a bit of bits for later reference, via any hardware mechanism.??

31.flip-latch?

flip-Latch is a logic device that remembers its input at the time clock transitions. flip-Latch can handle a single bit or a group of bits in parallel.?

32.PWM pulse width modulation

A digital control technique wherein the process or adjusts the duty cycle of a sequence of fixed width pulses. Unlike other modulation techniques, PWM is used more to control external analog signals or mechanical devices than to transmit data.?

33.integrator

The circuit that the integral of output signal and the input is direct ratio is integral circuit. Integral circuit convert the rectangular pulse wave into sawtooth or triangle wave, and convert the sawtooth wave into. The conduction composed integral circuit is that the time constant of circuit is must larger than or amount to 10 times for the width of the input wave.?
