Perform AC Analysis curve to plot of RIAA equalization the response of the preamplifier. This is in OP AMPS FOR EVERYONE Appendix D Figure D12. Using Multisim

Answer the following questions:

Describe the operations of this preamplifier circuit and explain how these preamplifier circuits work with single-supply circuits in limiting low frequency resonating components from the signal?

Solution

Ans: here iam expalining about RIAA equalization the response of the preanpliier:

Practical Considerations:

Amplifier Distortion:

We also learnt that the Power, Voltage or Current Gain, provided by the amplifier is the ratio of the peak output value to its peak input value. However, if we incorrectly design our amplifier circuit and set the biasing Q-point at the wrong position on the load line or apply too large an input signal to the amplifier, the resultant output signal may not be an exact reproduction of the original input signal waveform. In other words the amplifier will suffer from what is commonly.

Common Emitter Amplifier:

Distortion of the output signal waveform may occur because:

Then amplifier distortion occurs because the amplifier is not linear and a type of amplifier distortion called  will result. Careful choice of the transistor and biasing components can help minimise the effect of amplifier distortion.
