IC LM2917 Frequency to Voltage Converter

IC LM2917 IC chip is designed specifically as a Frequency to Voltage Converter or Frequency to Voltage converter. In its use to applications Frequency to Voltage Converter IC LM2917 requires few external components. There are several examples of applications of Frequency to Voltage Converter IC LM2917 datasheet that is included in the LM2917 IC. In this article series Frequency to Voltage Converter IC also taken from the LM2917 datasheet. The advantages of single chip LM2917 Frequency to Voltage Converter is able to provide instantaneous volt output o at time of frequency change 0 Hz. Very easy to apply in measuring the output frequency with the formulation of single-chip Frequency to Voltage Converter VOUT = FIN x VCC x R1 x C1. Then the single-chip LM2917 Frequency to Voltage Converter This configuration requires only the RC only in frequency doubling. And has an internal zener regulator to aimlessly accuracy and stability in frequency-to-voltage conversion process.

Zero Crossing Detector

Zero Crossing Detector circuit is basically an application of a comparator. In the article series Zero Crossing Detector with Op Amp is built using a comparator of an Op Amp IC741/351. The process of detection of this comparator is mngamati 0Volt input signal crossing point by making reference value at comparator 0Volt. The output of the Zero Crossing Detector circuit with Op Amp is wave-shaped box that mengiterprestasikan teteksi result of the crossroads of 0 volt input signal.

Voltage to frequency converter

Changing the voltage to frequency scale in the design of an electronic device is sometimes necessary. The series of articles voltage to frequency converter with the XR 4151 is one jawabanny. Voltage to Frequency converter circuit with the XR 4151 is the idea of ​​time in college, when there are projects to create a tool to hatch chicken eggs. It will be my neighbor also write articles incubators chicken egg-based microcontroller AT89C2051 (tempoe doeloe). Maybe there are friends who still remember to this project. Back to the topic of voltage to frequency converter circuit with the XR 4151. IC XR 4151 is a major component of voltage to frequency converter (Voltage to Frequency Converter).

Doubler Digital Frequency

Doubler Digital Frequencycircuit includes a simple and easy to understand. Digital Frequency Doubler circuit application contained in the system electronics such as audio-producing organ, or keyboard. The function of this series Digital Frequency Doubler for multiplying two input frequencies. The process of multiplying 2 on scales in an organ in principle is like this series Digital Frequency Doubler. Example of rising to a ringing tone DO RE then electronically technique in it is by multiplying the two frequency bands such as this series Digital Frequency Doubler.

Audio Frequency Generator Circuit

Audio Frequency Generator or often known by AFG is a device electronics used to generate signals with audio frequency range. Audio Frequency Generator (AFG) in the market there are many variant, from the analog to the digital . Even the assembly also exists, in principle, AFG is the frequency generator with an audio range. Here is one set of Audio Frequency Generator (AFG) which can be a reference if you want to make a series of Audio Frequency Generator (AFG) . The series of Audio Frequency Generator (AFG) is to use IC L8038 as a signal generator it.

AFG

The series of Audio Frequency Generator (AFG) above has three output waveform that is, sine, square and triangle directly from the IC L8038. IC CD4066 and IC circuit Cd4017 a configuration circuit for waveform selector that can be set by pressing SW1. To adjust the working frequency is set by potentiometer R2.

10Hz - 60Mhz Frequency Meter

The frequency meter can be used to measure the frequency of 10 Hz-60Mhz. The frequency meter has a level of precision or resolution of 10Hz. The frequency meter can be used to measure the frequency of the oscillator, transmitter, frequency generator, cristal, and others during the working frequency trsebut devices in the range 10 Hz - 60MHz. Circuit frequency meter using PIC 16F628A dibagun and with the viewer of the LCD 16 × 2. Frequency meter circuit is working with the working frequency of 4MHz crystal. The series is an electronic frequency meter is quite simple to make. The following picture of the frequency meter circuit.

The series of frequency meters above basically works with the source voltage 5VDC. In this series of 7805 voltage regulator has been installed, so it can be operated with a voltage of 5 - 15VDC.
