Simple Speaker Turn-on Delay Circuit
Today we are going to introduce you to a Simple Speaker Turn-on delay Circuit. Imagine after you finish building your own OCL power amplifier circuit. But every time you turn it on, within the first 3 seconds, you hear a loud “tlub” sound from a speaker. Wouldn’t you feel annoyed by that sound? Apart from … Read more

Small Signal Amplifier Circuit Using Transistor
We are going to learn how to design a small signal amplifier circuit using transistors in a simple way, with class A amplifier form. Read more
Experiment with adjustable transistor circuits partially on-off
In the previous articles, we learned about using a transistor as a switch, that was, either completely on or off. But circuits such as the audio amplifiers will require the transistor to be partially on, which is very interesting. But it can be quite a difficult subject for beginners who just started learning electronics to … Read more
