Two staged RC coupled Amplifier

-

Purpose: -

(a) Study the amplifier combined with two RC components.

(b) Set the curve of the frequency response. Therefore determines the bandwidth.

 

Requirements: -

Transistor, function generator, resistors, capacitors, controlled power supply, multimeter, breadboard, connecting cables, etc.

 Circuits Diagram:-


Opinion: -

The amplifier is the building block for many electrical systems. A single-stage amplifier is not enough to build an effective electronic system.

When no. The amplifier class is used sequentially called multistage. Amplifier (or) amplifier with cascaded high gain can be obtained from multistage amplifying. Demonstrates how to pair a phase 2 amplifier using the RC-coupling system. This is the most widely used method.

In this system, a signal built across the resistor RE (R2) of the first phase is connected below the second phase with a capacitor CE (C2). The coupling capacitor prevents the DC power of the first phase from reaching the base of the second phase. Like saying no. With the increase in categories, profit will also increase.

Tabular column:-

 

Frequency in Hz

 

o/p voltage

Vo(In volts )

 

Gain=Vo/Vin

 

 

 

 

 

 

 

 

 


Process: -

 1) Check the resources before making a connection.

2) The connection is made as shown in the circuit diagram.

3) Change the Vcc dc supply voltage and save Vcc = 10v.

4) Connect the DMM directly to the generator note function below the I / p voltage VI at a frequency of 1 kHz.

5) Now with different values ​​the recordings of the corresponding output power Vo.

6) Calculate the profit

7) Plot gain graph vs. usually.

8) From the graph to calculate bandwidth.

Nature of Graph:-



 

Result: -

we studied two categories of integrated RC enlargement. And I built a frequency response frequency and found the bandwidth. B = ………. kHz.

Image
Aim:-  To determine the value of Stefan's constant. Apparatus:-  Black body radiation unit, Ammeter, Voltmeter, connecting wires, DC source. Theory:-  Stefan's constant: A physical constant denoted by  σ , is the constant of proportionality in the Stefan's-Boltzmann law- the total intensity radiated over all wavelength increases as the temperature increases Procedure:- 1) The electrical connections are made as shown in the circuit diagram. 2) Copper black body radiator is preheated to  30 0 C   by setting maximum voltage in the power supply 3)after the temperature indicator indicates a temperature of about    30 0 C , the voltage is reduced to some value  4) increase the voltage in steps of 0.2 V and note down the current, hence calculate power l. 5) Determine the value of Stefan's constan t. Observations:-  Room temperature t o =t+273=......of 2) surface area of the black body  A=4π r 2  = .........m square Calculati...

Image
Aim:-  To draw the frequency response of Pre-emphasis & De-emphasis networks. Introduction:- Educational trainer a useful kit for the demonstration of Pre-emphasis & De-emphasis at different time constants & plot the graph of the frequency response of Pre-emphasis and De-emphasis networks. The kit consists of 200 Hz-20 kHz audio oscillator 70µ sec & 50µ sec De-emphasis networks.  Pre-Emphasis Circuit Diagram:- DE-Emphasis Circuit Diagram:- Theory:- Pre-emphasis refers to boosting the relative amplitudes of the modulating voltage for higher audio frequencies from 2 to approximately 15 kHz . De-emphasis means attenuating those frequencies by the amount by which they are boosted.  However, Pre-emphasis is done at the transmitter and De-emphasis is done in the receiver. The purpose is to improve the signal-to-noise ratio for FM reception. A time constant of 75µ sec is specified in the RC or L/Z network for Pre-emphasis and De-emphasis. Tabular colu...
