    What are the advantages of negative feedback

    deepakgenius716

    (i) Highly stabilized gain. (ii) Reduction in non-linear distortion. (iii) Increased bandwidth,i.e.,improved frequency response. (iv) Increased stability of circuit. (v) Less amplitude distortion. (vi) Less frequency distortion and less phase distortion. (vii) Increases input impedance and decreases output impedance. In other words,the input and output impedance and decreases can be modified as required. (viii) Reduces noise and less harmonic distortion. (ix) The transfer gain Af of…

    Differences between positive feedback and negative feedback

    deepakgenius716

    POSITIVE FEEDBACK (i) If the feedback signal (voltage or current) is applied in such a way that it is in phase with the input signal and thus increases it,then it is called a positive feedback. (ii) it is a regenerative or direct feedback. (iii) Positive feedback increases the gain of amplifier. (iv) It produces excessive distortion. (v)…

    DESCRIPTION OF ELECTROLYTIC CAPACITOR

    deepakgenius716

    Electrolytic capacitors are capacitors in which one or both of the “plates” is a non-metallic conductive substance,an electrolyte.Electrolytes have lower conductivity than metals,so are only used in capacitors when metallic plate is not practical,such as when the dielectric surface is fragile or rough in shape or when ionic current is required to maintain the dielectric integrity.The flow…

    LINEAR VERSUS SWICTHING POWER SUPPLIES

    deepakgenius716

    Switching and linear regulator use fundamentally different techniques to produce a regulated output voltage from an unregulated input.Each technique have advantages and disadvantages.So the application will determine will determine the moist suitable choice. Linear power supplies can step-down an input voltage to produce a lower output voltage.This is done by operating a bipolar transistor or…

    Explain the applications of spectrum analyzer

    deepakgenius716

    The spectrum analyzer is a powerful tool and has many applications.To those who have never used the instrument,these applications may not be readily apparent.To illustrate  some of the applications,the following signals,their applications their descriptions and spectrum analyzer display,will be presented. (i) Pure sinusoid with no Modulation or Harmonic Distortion-This signal is characterized by a signal…

    With the aid of block diagram,explain the working of Heterodyne spectrum analyser

    deepakgenius716

    A wave analyser using the Heterodyning principle is shown in the block diagram of fig.In this,the input signal to be analysed is Heterodyned to a higher intermediate frequency (IF) by an internal local oscillator.Tuning the local oscillator transfers the various signal frequency components into the passband of the IF amplifier. The working frequency range of…
