Why gain increases in low frequency region in BJT?

Because Beta (current gain) in a transistor is inversely proportional to frequency. Hence it increases as frequency decreases. Also the ac voltage gain is directly proportional to Beta.


What is proportional control?

Proportional controllerA proportional controller is a type of a feed back controller where the difference between the measured output and the input (the desired output) is multiplied with a proportional gain and feed to the system.


How is a proportional and non-proportional relationship different?

Proportional is when it is proportional.


What is Proportional Band?

In practice, the controller output is limited, either by its own limitations or by the limitations of the corresponding actuator. Let umax and umin denote the minimum and maximum output of the controller. The proportional band of the controller is then defined as:In the ideal case, a controller can have an unlimited output. The proportional band (PB) is then defined as:This definition of proportional band is often used instead of the controller gain. The value is expressed in percent (%).


If A is proportional to B square and B is proportional to C Square then A is proportional to?

A is proportional to C4.


Is 120-xL proportional or not proportional?

It is an expression, not an equation and so cannot be proportional nor non-proportional.


If the diameter of an objective mirror is doubled its light-gathering power becomes?

Just like any antenna used to collect electromagnetic energy at any other frequency, the 'gain' is proportional to the antenna's area. Since the area varies as the square of the collector's diameter, doubling the diameter increases the gain by a factor of 22 = 4. The corresponding increase in gain is 6 dB.


What is directly and inversely proportional relationship?

Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.


How does proportional representation affect party organization?

Proportional representation can lead to the fragmentation of political parties, as it allows smaller parties to gain representation. This can require parties to form coalitions in order to govern, leading to more complex party structures. Additionally, parties may need to broaden their appeal to attract a wider range of voters in order to secure enough seats in a proportional voting system.


An RF amplifier amplifies the incoming signal by 200 times Calculate the power gain of this amplifier in dB?

If an RF amplifier amplifies the incoming signal by 200 times, the power gain of the amplifier is +25.9 dB. Power is proportional to voltage squared, so the power gain is 400. The decibel scale is 3 times log2 of the power change.
