What is Analog Signal and Digital Signal? What is Analog Signal and Digital Signal? - In communication systems, a signal means a time varying electriÂcal signal which contains all information or intelligence. The anaÂlog signal…
What is an Operational Amplifier?: An Operational Amplifier is a dc amplifier having a high gain, of the order of 104 - 108. Such an amplifier can perform summing, integration, differentiation, or act as comÂparator…
What is an Inductive Transducer?: Inductive Transducer may be either of the self generating or the passive type. The self generating type utilizes the basic electrical generator principle, i.e. a motion between a conductor and…
What is an Ideal Diode - Working and its V-I Characteristics: Diode is a two terminal device that permits only unidirectional conduction. It conducts well in the forward direction and poorly in the reverse direction.…
What is Alphanumeric Codes? - ASCII code, EBCDIC Code: In order to communicate, we need not only numbers but also letters of alphabet, punctuation marks and other special characters. These codes are called alphanumeric codes.…
What is Active Filters and types of active filters: Active Filters is a circuit that is designed to pass a specified band frequencies while attenuating all the signals outside that band. It is a frequency selective circuit. The…
What is Active Components and Passive Components? All electronic circuits, however complicated, contain a few basic components (generally speaking, only five)—three passive and two active components. Though passive components by themselves are not capable of…
What is a thermistor? - Definition, Symbol and V-I Characteristics: The word thermistor is a combination of thermal and resistor. A thermistor is a resistor with definite thermal characteristics. Most thermistors have a negative temperature…
What is a Temperature Transducer?: Temperature Transducer is one of the most widely measured and controlled variable in industry, as a lot of products during manufacturing requires controlled temperature at various stages of processing. A…
What is a Power Converter? Solid-state power converter are employed for obtaining the approÂpriate form of electrical energy such as direct current or adjustable-frequency alternating current (required to operate most electronic circuits and motor drives)…
