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....

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.

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.

The bandwidth of a resonant circuit is defined as the distance between the two -3dB rolloff points in the response curve.

A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.

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.

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.

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.

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.

The Gaussian curve is the Normal distributoin curve, the commonest (and most studied) of statistical distributions.

A frequency curve has a major disadvantage of not showing the exact values of the distribution. it is also difficult to compare different data sets. A frequency curve has the greatest advantage of showing the skewness of the distribution that is whether it is positively skewed, negatively and symmetric distribution.

The "frequency curves" are called waves. The highest point of a wave is the crest.

For example , if you are conducting the RC coupled the amplifier, the will be frequency response curve , due to which cc ,cce and ccb of internal capacitance of the transistor , In that you have take the gain as 3db .. at frequency response ,they will ask why you have to select the #db.. instead of 3db you select \$ or 6db's .. I will tell the reason later !!! Bye

The main utility of a cumulative frequency curve is to show the distribution of the data points and its skew. It can be used to find the median, the upper and lower quartiles, and the range of the data.

The meniscus is the curve at the liquid's surface. It is produced in response to the surface of the container or another object.

There is no histogram below.However, the area under the curve for any histogram is the total frequency.

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.

A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.

the toes curve inward and the foot everts Or no response !!

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

It will show you whether it is a constant rate or if it speeds up or slows down.

An ogive is a cumulative relative frequency diagram. Interpolation is definiting the midpoint (50%) of this line
