Dc and ac analysis of Differential amplifier?
DC Analysis: For this analysis, frequency is made zero and the voltage of the source is increased in small steps from 0V.And the output voltage is plotted. So, finally we get a Vout vs Vin curve. AC Analysis: In this analysis, we choose an AC source. We keep the Offset voltage = 0V, AC voltage or small signal voltage = 2V (You can take any voltage you wish and it doesnt matter). So, to plot the ac response or frequency response of the circuit, increase the frequency in steps and note the output voltage. from this analysis , we can find the gain of the circuit over frequency.
What do you understand by bandwidth of a parallel resonant circuits?
The bandwidth of a resonant circuit is defined as the distance between the two -3dB rolloff points in the response curve.
Can use 7.5mfd capacitor for a 5mfd capacitor?
Yes and no. 7.5 microfarads is close to 5 microfarads, so it might be possible to substitute. It depends on the particular circuit design requirements. If you are talking de-coupling or power supply usage, then you can probably substitute. If you are talking filter applications, such as a high pass filter, then you probably cannot substitute without changing the frequency response curve.
What is the Time domain analysis of control system?
Time domain basically means plotting a curve of amplitude over thr time axis. A given function or signal can be converted between the time and frequency domains with a pair of mathematical operators called a transform. An example is the Fourier transform, which decomposes a function into the sum of a (potentially infinite) number of sine wave frequency components. The 'spectrum' of frequency components is the frequency domain representation of the signal. The inverse Fourier transform converts the frequency domain function back to a time function.
What is the c curve and d curve in MCB?
c curve & d curve mcb difference
What is the purpose of determining frequency response?
frequency response curve helps us to find the bandwidth of particular amplifier circuit. Bandwidth is the range of frequency at which the amplifier works better....
What is the scientific meaning of the phrase 'frequency response'?
The scientific meaning of the phrase "frequency response" refers to a curve used in physics or engineering to represent the output to input ratio of a transducer as a function of frequency.
Definition of half-power frequency?
The frequency on an amplifier response curve which is greater than the frequency for peak response and at which the output voltage is 1/√2 (that is, 0.707) of its midband or other reference value.
Frequency response curve of RC coupled amplifier?
at low frequency less than 50hz the voltage gain decreases with decreasing frequency and at mid frequency{50hz to 20khz} the voltage gain is uniform because resistor value are independent of frequency change and at the high frequency votage gain falls.
Drawbacks of constant k type filters?
Drawback of the constant K type filter is that at the cut of frequency , its attenuation is a steady curve .. quick response is lacking in it an ideal filter should have a sharp response curve.
What is Frequency curve?
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
How is a frequency curve in statistics different from a frequency polygon?
In order to plot the points on either the frequency polygon or curve, the mid values of the class intervals of the distribution are calculated. Then the frequencies with respect to the mid points are plotted. However in a frequency curve the points are joined by a smooth curve, where as in a frequency polygon the points are joined by straight lines. Apart from this major difference, a frequency polygon is a closed figure where as the frequency curve is not.
What is cumolative frequency curve?
A cumulative frequency curve is a graph that shows the cumulative frequency of a data set. This type of graph can present data, such as medians and quartiles. Another name for this curve is an Ogive.
What is gaussian frequency curve?
The Gaussian curve is the Normal distributoin curve, the commonest (and most studied) of statistical distributions.

A Is the market supply curve for a product more or less price elastic than the supply curve of one of the firms in the market Why?
The market supply curve of a product is more price elastic than the supply curve of one of the firms in the market. The reason is that for any given price change, the market quantity response reflects the change in output of all the firms in the market.
What uses rectangles to show frequency distribution?
