The push pull amplifier is a power amplifier and is frequently employ in the output stages of electronic circuit. It is use when high output power is require at high efficiency. So push pull amplifier figure you can see in the below. Two transistors Tr1 and Tr2 placed back to back are employ. Both the … Read more
Here we will discus about the different types of modulation. So there are three type of modulation, and those three different types of modulations are (1) Amplitude Modulation (2) Frequency Modulation (3) Phase Modulation. Modulation is the process of changing the characteristic of a carrier signal ( Amplitude, Frequency, Phase ) in accordance with then … Read more
When a transistor to be connect in a circuit will require 4 terminals, 2 for the input and two for the output. We will share one terminal for both the input and output terminals and we will overcome this problem. So a transistor can be connect in three type configuration. Common base ( CB ) … Read more
A transistor circuit having more than one stage of amplification is known as a multistage transistor amplifier. The number of single amplifiers is linked to the cascade arrangement. That is the output of the 1st stage is connected to the input of the 2nd stage through a suitable coupling device and so on. … Read more
What is Single Stage Transistor Amplifier? – When only a single transistor is used with an associated circuit to amplify a weak signal, the circuit is known as a single stage transistor amplifier. The single stage transistor amplifier consists of a transistor, bias circuit and other auxiliary components. there are many stages in a … Read more
Filter is an electronic circuit which converts the pulsating d. c. signal into pure d. c. signal. In other way, A filter circuit is a device which removes the a. c. components to d. c. to reach the load. A filter circuit is generally a combination of inductor ( L ) and capacitor ( C … Read more
What is transistor in electronics ? Transistor is an electronic device which transfer the signal from low resistance region to high resistance region. For what is the filter circuit? click here A transistor is a semiconductor device which has two junction, three layer and three terminals. The three terminals are Emitter, Base, and Collector. It … Read more
Definition rectifier – Rectifier is an electronic device which converts alternating current (a. c.) in to direct current (d. c.) is known as rectifier. There are many application for example in electronic circuit d. c. supply is need. So the main a. c. supply is rectified by using crystal diodes. There are two types of … Read more
Here, you will get to see semiconductor and its types. Semiconductor are a type of substance in which there is a resistivity (10-4 to 0.5 ohm) between the conductor and insulator. Such as germanium, silicon, selenium, carbon. However semiconductors are more broadly defined on the basis of energy bands. As you know semiconductor is such … Read more
Here we are going to study the classification of electronic materials. And you can also say difference between conductor, insulator and semiconductor, Then let’s start this topic. Depending on the number of valence electrons, materials are classify in to three types. Valency < 4 ⇒ Conductor/ metals Valency = 4 ⇒ Semiconductor Valency > 4 … Read more
