What is Operational Amplifier (Op-Amp)? How Op-Amps Work? 1/2

In this video, I will explain the working principle and structure of operational amplifiers, which we can encounter in many places in our daily life and which gain by amplifying the electrical signal. I will explain the types of operational amplifier circuits in the next video. Almost all of the signals to be processed by electronic systems are low amplitude, that is, weak signals.

There are many electronic systems in our lives that amplify these weak signals and make them usable. For example; Operational amplifiers are used in amplifiers that we amplify our voice or a music with a microphone and give it to the speaker. In addition, for the diagnosis of heart rhythm disorders and vascular diseases, the electrical activity as a result of the heart rhythms that occur during the contraction of the heart is graphically recorded and we can see the shape on computer screens by raising it, electrodes attached to the skin on the chest, arms and legs area and electrocardiograph (ECG) devices used in the detection of abnormal conditions operational amplifiers are also used.
