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.
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.
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 load line concept?
A load line is used in graphical analysis of nonlinear electronic circuits, representing the constraint other parts of the circuit place on a non-linear device, like a diode or transistor. It is usually drawn on a graph of the current vs the voltage in the nonlinear device, called the device's characteristic curve. A load line, usually a straight line, represents the response of a linear circuit connected to the nonlinear device in question. The operating point(s) of the circuit are the points where the characteristic curve and the load line intersect; at these points the current and voltage parameters of both parts of the circuit match
What is transfer function?
A transfer function (also known as the system function[1] or network function and, when plotted as a graph, transfer curve) is a mathematical representation, in terms of spatial or temporal frequency, of the relation between the input and output of a linear time-invariant system with zero initial conditions and zero-point equilibrium. With optical imaging devices, for example, it is the Fourier transform of the point spread function (hence a function of spatial frequency) i.e. the intensity distribution caused by a point object in the field of view. An alternative brief definition is "a mathematical function relating the output or response of a system such as a filter circuit to the input or stimulus"[2].
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....
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.
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.
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.
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.
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 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.
What is gaussian frequency curve?
The Gaussian curve is the Normal distributoin curve, the commonest (and most studied) of statistical distributions.
