You may already know that Amplifier circuits are two-port electronic circuits that receive electric power from a power supply and increase the amplitude of the signal at its output in regular terms. But do you know how to make amplifier circuits using Op-amp and MOSFET or how do they work? Inverting amplifiers are one of the most popular operational amplifier circuits that … [Read more...] about Amplifier Circuits Using Op-amp Inverting, Non-Inverting and MOSFET

What Is Oscilloscope Bandwidth
As the frequency of the test signal is increased, the amplitude of the seen signal lowers by -3 dB or 70.7 percent of its real value, which is known as oscilloscope bandwidth. The fundamental ability of an oscilloscope to measure a signal is determined by its bandwidth. The oscilloscope's capacity to accurately show the signal reduces as the signal frequency increases. … [Read more...] about What Is Oscilloscope Bandwidth
Condenser Microphone Amplifier Schematic Using BEL 1895 IC
Here I will show you an audio amplifier circuit that can be used for walkie-talkies, low-power transmitters, and packet radio receivers. A condenser mic audio amplifier gives good quality audio of 0.5 watts at 3 volts. Here we are going to make use of BEL 1895 (Bharat Electronics Limited 1895) audio amplifier IC which is also a noise-free amplifier IC. We are … [Read more...] about Condenser Microphone Amplifier Schematic Using BEL 1895 IC
What Is the Purpose of Protocols in Data Communications
Protocols provide rules and functionalities that define how a message is transmitted, ensuring consistency and proper standard across a network. Also, it defines and represents the implementation and access rules of the system. What Is the Purpose of Protocols in Data Communications Protocols in data transmission can be defined as a set of rules to ensure a standard … [Read more...] about What Is the Purpose of Protocols in Data Communications
What Is DTMF | Basic Principle and Use of DTMF in Communication
What is DTMF (Dual Tone Multi Frequency)? DTMF is a common communication term for touch-tone phones. The tones formed when dialing on the keypad (DTMF digits or DTMF number) on the phone can be used to characterize the digits, and some different tone is used for each digit. DTMF signaling is mainly used in DTMF phones, and telephone switching systems.Yet, there is … [Read more...] about What Is DTMF | Basic Principle and Use of DTMF in Communication
