Introduction To Power Amplifiers An amplifier system consists of signal pick-up transducer, followed by a small signal amplifier(s), a large signal amplifier and an output transducer. A transducer is used to convert one form of energy into another type. For example a microphone is used to convert acoustical energy into electrical energy. Conversely, a loudspeaker […]
The above video claims you can make a pocket size FM radio station and the highlight is you dont need an antenna to do this. A small battery is enough to power and it will last for 5 to 7 hrs. This small battery powered FM radiostation even dont need a antenna to broadcast your
Here’s a descriptive video on How to perform Photo Etching on a PCB. This video also is based on “home PCB making techniques” – which helps electronic minds(electronics projects) to develop PCB’s from home. Such techniques are always interesting as an experiment & a means to save money!
Watch this amazing video on How to etch PCB using Ferric Chloride. You can do this in home in a simple way. Me too have done etching in home using Ferric Choride before & I am sure you will love this post.
Watch the above video to see a simple demonstration on How to Make a Fireball Shooter. You can do it as a simple project!
Do you wanna learn How to make a PCB -Printed Circuit Board using a laserjet printer? Its simple! watch the above video! What you all need is a circuit diagram, copper clads, sand papers, a printer, computer & an iron! You are done! I will explain the entire process later in words!
Learn how to de-solder electronic connections from the above video. He explains in the video how to remove the solder using a soldering iron alone, then using a desolder machine. He also explains the way of removing complex & thick solders using a combined action of soldering irons heat & a desolder. Usually a combined
Watch the video given below to get a better idea on how LED works? Â A light emitting diode (LED) is known to be one of the best optoelectronic devices out of the lot. The device is capable of emitting a fairly narrow bandwidth of visible or invisible light when its internal diode junction attains a
Inverter systems can be in-corporated with generator systems to attain longer run-time when there is a cut in the mains power supply.The essential and critical loads require undisturbed power supply when the mains AC power supply falls for extended periods.The inverter can be used to power the critical and essential loads when the power supply
In various countries the frequency bandwidths specified for the GSM services are GSM-400, GSM-800, GSM-900, GSM-1800 and GSM-R.The GSM-900 and the GSM-1800 are the most widely used frequency bandwidths in different parts of the globe. The GSM-900 has a down link frequency range of 935-960 MHz and an up link frequency of range of 895-915
Nowadays most of the inverters available in the market utilizes the PWM(Pulse Width Modulation) technology.The inverters based on PWM technology are superior in many factors compared to other inverters designed using conventional technologies. The PWM based inverters generally use MOSFETs in the output switching stage.In such cases the inverters are generally termed as PWM MOSFET
An inverter is used to produce an un-interrupted 220V AC or 110V AC (depending on the line voltage of the particular country) supply to the device connected as the load at the output socket. The inverter gives constant AC voltage at its output socket when the AC mains power supply is not available. Let’s look
We have already discussed in detail about the basics on operational amplifier, its block diagram, symbol, different characteristics, and its circuit diagram (Refer:- Op Amps-Operational Amplifiers). In this post, we will be discussing about the 741 IC, one of the most popularly used op-amp IC. About the uA741 Op-amp IC The 741 IC was designed
VOIP (Voice over Internet Protocol) is a protocol used for the transmitting voice through the Internet or other packet-switched networks. VoIP is often used to refer to the transmission of voice . VoIP is also known as Internet telephony, Broadband Phone. VOIP is pronounced as “voyp”. Companies providing VoIP service are commonly referred to as
