Introduction of Function Generator Working with Block Diagram

Eltronicschool. - Maybe you will not foreign again with the function generator in electronic field now. This device will give you the output signal like sinous, square, and pulse for your project.

In this time we will show you the introduction of the function generator working with the block diagram look like in Figure 1 below.

Blog Diagram of Function Generator

Figure 1. Block Diagram of Function Generator (Source: Circuitstoday.com)

Description

This is the function generator working for you. Accordingly Circuitstoday blog describe that a function generator is a signal source that has the capability of producing different types of waveforms as its output signal. The most common output waveforms are sine-waves, triangular waves, square waves, and sawtooth waves. The frequencies of such waveforms may be adjusted from a fraction of a hertz to several hundred kHz.

The block diagram of a function generator is given in the figure. In this instrument, the frequency is controlled by varying the magnitude of the current that drives the integrator. This instrument provides different types of waveforms (such as sinusoidal, triangular and square waves) as its output signal with a frequency range of 0.01 Hz to 100 kHz.

The frequency controlled voltage regulates two current supply sources. Current supply source 1 supplies a constant current to the integrator whose output voltage rises linearly with time. An increase or decrease in the current increases or reduces the slope of the output voltage and thus controls the frequency.

Tools: Introducing for 4 Band Resistor Calculators

Eltronicschool. - The most popular component in electronic devices is resistor. There are many kinds of resistor provided in this time, one of them is 4 band resistor calculator.

In this season we will show you information about the introducing for 4 band resistor calculators.

Introduction

A resistor is a perhaps the most common building block used in circuits. Resistors come in many shapes and sizes this tool is used to decode information for color banded axial lead resistors.


4 Band Description

The number of bands is important because the decoding changes based upon the number of color bands. There are three common types: 4 band, 5 band, and 6 band resistors. For the 4 band resistor:

Band 1 – First significant digit. 

Band 2 – Second significant digit 

Band 3 – Multiplier 

Band 4 – Tolerance


Resistance Value

The first 4 bands make up the resistance nominal value. The first 2 bands make up the significant digits where: 

black – 0 

brown – 1 

red – 2 

orange – 3 

yellow – 4 

green – 5 

blue – 6 

violet – 7 

grey – 8 

white – 9


The 3rd band or multiplier band is color coded as follows: 

black – x1 

brown – x10 

red – x100 

orange – x1K 

yellow – x10K 

green – x100K 

blue – x1M 

violet – x10M 

grey – x100M 

white – x1G 

gold – .1 

silver – .01


An example of a resistance value is:

band 1 = orange = 3, 

band 2 = yellow = 4, 

band 3 = blue = 1M


value = 34*1M = 34 Mohm


Resistance Tolerance

The fourth band is the tolerance and represents the worst case variation one might expect from the nominal value. The color code for tolerance is as follows: 

brown - 1% 

red - 2% 

orange - 3% 

yellow - 4% 

green - .5% 

blue - .25% 

violet - .1% 

gray - .05% 

gold - 5% 

silver - 10%


An example calculating the range of a resistor value is:



If the nominal value was 34 Ohm and the 4th band of the resistor was gold (5%) the value range would be nominal +/- 5% = 32.3 to 35.7

Circuit Schematic Smart Master/Slave Switch using SMPS Module 5-V/3-W Type (HLK-PM01)

Eltronicschool. - This is one of the power supply project part in this time to show you one of the circuit schematic of Smart Master/Slave Switch using SMPS Module 5-V/3-W Type (HLK-PM01).

In this project with circuit schematic of Smart Master/Slave Switch using SMPS Module 5-V/3-W Type (HLK-PM01), you will show an inexpensive and easy-to-build master/slave switch for integration into powerstrips for the automatic switching of “slaves” upon the status of the “master.” 

Circuit Schematic

  1. SMPS Module 5-V/3-W Type (HLK-PM01)
  2. Transformer
  3. Resistors
  4. Transistors
  5. Diode
  6. Capacitors
  7. Relay
  8. LED
Description

Circuit schematic like in Figure 1 above is Smart Master/Slave Switch using SMPS Module 5-V/3-W Type (HLK-PM01). The main component in this circuit schematic is SMPS Module 5-V/3-W Type (HLK-PM01).

How it works

According Electroschematics site describe that the circuit is designed around two key components: a current transformer and a compact SMPS module. The current transformer (CT) is a 5-A/1,000:1 type with a built-in “burden resistor,” and the SMPS module is a 5-V/3-W type (HLK-PM01). The current transformer is specifically designed for monitoring current, and you can wind a few turns of mains-insulated wire through its core to derive a useable output from the secondary. When the current transformer senses plentiful load current from the master unit, an electromagnetic relay (RL1) wakes up to power everything connected to the slave and falls asleep again when the master unit is turned off.

How it works

According Circuitstoday site describe the frequency to be counted is connected to digital pin 12 of the arduino. pulseIn() function is used here for counting the frequency connected to pin 12. pulseIn() function counts the number of pulses (HIGH or LOW) coming to a particular pin of the arduino. The general syntax of this function is pulseIn(pin, value, time) where pin is the name of the pin, value is either HIGH or LOW and time is time for which the function to wait for a pulse. The function returns zero if there is no valid pulse with in the specified time. The pulseIn() function can count pulses with time period ranging from 10 μS to 3 minutes.
