Frequency response of bjt amplifier?
All amplifier typically exhibit a band-pass frequency response. The cut off frequency in the low end is usually determined by the coupling band bypass capacitor .and the high frequency limit is typically determined by internal capacitances in the transistor itself.
What will happen if the signal frequency is greater than cut-off frequency in a waveguide?
If the signal frequency exceeds the cut-off frequency in a waveguide, the wave will not propagate through the waveguide and will be attenuated. This is because the waveguide is designed to support only certain modes of propagation, and frequencies above the cut-off do not satisfy the waveguide's mode conditions. Instead, the signal will either reflect back or be absorbed, leading to a loss of signal strength.
What is the voltage across collector to emitter when transistor is in cut off region?
In the cut-off region of a transistor, the base-emitter junction is not forward-biased, meaning the transistor is effectively turned off. As a result, no current flows from collector to emitter, and the voltage across the collector to emitter (V_CE) is approximately equal to the supply voltage (V_CC) connected to the collector. Therefore, V_CE is at its maximum value, close to V_CC, indicating that the transistor is not conducting.
Why cut off frequency is called half power frequency?
Cut off frequency is that frequency at which the power output of the circuit reduces to half of its power in pass band. Power (P)= Current2 X Resistance. so to reduce the power by half we need to reduce the current by 1/sqrt{2} = 0.707 = 3 db. So it's also called half power frequency. http://enter4joy.com
What are cut-off and saturation points in a dc load line?
The cut-off point is the exact point where the load line crosses with the vector axis. The saturation point is the point where the load line intersects with the collector current axis.
What are the application of low pass and high pass filter?
they are used in industries so to able you to work on particular frequency and cut the other for e.g if you are working for high frequency then low frequency will be cut and vise versa
The value of r when a transistor is biased to cut off is -?
Collector-to-Emitter resistance is high when the transistor is biased off.
How High pass filter circuits works?
A High Pass Filter is an Electronic Filter that passes high frequency signals but Attenuates (reduces the Amplitude ) of Signals with frequencies lower than the cut-off Frequency
Is a high pass filter and a low pass filter the same thing?
Yes, they are both filters. But their frequency characteristics are different. This is the main reason why they are given different names. A high-pass filter passes frequencies higher than its cut-off frequency, and stops those that are lower. A low-pass filter passes frequencies lower than its cut-off frequency, and stops those that are higher.
Frequency response of bjt amplifier?

What is alpha cut of frequency?
it is the frequency at which the current amplification drops 3dB below its low frequency value.
Relation between cutoff frequency and bandwidth?
The relation between cut off frequency (fc) and band width is as follows: fc=Q*B.W where Q=(fL*fH)^1/2/(fH-fL) Q is quality factor. fL is low frequency. fH is high frequency.
What are the ratings and certificates for Death Collector - 1988?
Death Collector - 1988 is rated/received certificates of: UK:15 (cut)
If the frequency of light is cut in half what will happen to the energy?
The energy of the light is directly proportional to its frequency according to the equation E=hf, where E is energy, h is Planck's constant, and f is frequency. Therefore, if the frequency of light is cut in half, the energy of the light will also be halved.
