Learning to Design an Electronic Circuit Properly 

Executive Summary By Frederic C Padilla

Usually, circuit is made with some basic parts such as capacitors and resistors. Those basic parts are then built into some several combination that structure building blocks for other circuits.

Some people who have enough experiences might not find any difficulty in designing electronic circuit. First, you need to know well about the characteristics and behavior of either intermediate or advanced components of electronic circuit. Sometimes, you can find sample circuits that will help you get more information in using the parts. Some parts that usually contain this information are including semiconductors such as diodes, transistors, as well as op-amps.

Second, you should also learn more about some basic circuits used in many kinds of electronic devices. You will also get this information easily from any basic electronics text. For example, you can have more practices in modifying a Light-Emitting Diode (LED) circuit.

Simple Ways To Understand The Filter Capacitors In Electronic Circuits

Executive SummaryBy Jestine Yong

You could see mica capacitors, ceramic capacitors, tantalum capacitors, aluminum electrolytic capacitors, paper capacitors and etc. Electronic Field - Act as filter to remove ripple in power supplies;

- As inter stage signal coupling capacitors- A capacitor will not pass DC, but an AC signal will go through;

- Tuning resonant circuits, oscillator circuits;

In today's article I'm going to talks about capacitor act as filter to remove ripple from power supplies. Usually, the filter includes one or more capacitors. The capacitors are then placed between the DC line and ground. This unwanted noise signal can cause problems in electronic circuit. If all capacitors checked okay I would then move on to another circuit. Why not one filter capacitor is enough for each DC line voltage? The answer is that the big filter capacitors (large value) at the secondary side of power supplies is to smooth the DC and remove unwanted lower frequency noise.
