Music Amplifiers have always intrigued us due to their massive amplifying capabilities which completely changes the dimensions of the delivered music outputs. Fundamentally it’s the power of the amplifier that’s always on the scanner and we find folks getting too obsessed by the power rating of their procured amplifier unit. Introduction However many of us …Read more
The post explains how to test mosfets using multimeter through a set of steps, which will show help you to accurately learn the good or faulty condition of a mosfet Mosfets are Efficient but Complex Devices MOSFETs are outstanding devices when it comes to amplifying or switching of various kinds of loads. Though transistors are …Read more
VU meter or a volume unit meter circuit is a device used for indicating the music volume output from an amplifier or a loudspeaker system. It may be also considered as a device for displaying the PMPO of the amplifier at a particular volume setting. It is also called music level indicator circuit since the …Read more
In this article we learn how to build a digital voltmeter and a digital ammeter combined circuit module for measuring DC volts and current through different ranges, digitally. Introduction Electrical parameters like voltage and current are inherently associated with electronics and with electronic engineers. Any electronic circuit would be just incomplete without appropriate supply of …Read more
In this post we will talk about a couple of easy yet very handy little circuits in the form of frequency meter and capacitance meter using the ubiquitous IC 555. How Capacitors Work Capacitors are one of the main electronic components which come under the passive component family. These are extensively used in electronic circuits …Read more
