The h-parameter model assumes linearity and is mainly used for low and mid-frequency analysis where the transistor operates in the active region. At high frequencies, the parasitic elements like the capacitances associated with the device cannot be neglected, leading to inaccurate results. High-frequency models like the hybrid-pi model or S-parameter models are more suitable for analyzing transistors at high frequencies.

What are the waves that have high frequency also have high?
High frequency waves also have high energy. This means that waves with shorter wavelengths (higher frequency) carry more energy than waves with longer wavelengths (lower frequency). Examples of high frequency, high energy waves include gamma rays and X-rays.
A high pitch always corresponds to?
A higher frequency of sound waves.
Does a low pitched note have a high frequency?
No, a low pitched note has a low frequency. The pitch of a sound is determined by its frequency, with low frequency sounds corresponding to low pitched notes and high frequency sounds corresponding to high pitched notes.
The frequency range 30MHz - 300MHz is?
The frequency range 30MHz - 300MHz is part of the VHF (Very High Frequency) spectrum. It is commonly used for applications such as FM radio broadcasting, air traffic control, and television broadcasting. It falls between the HF (High Frequency) and UHF (Ultra High Frequency) ranges.
Which will have more energy a high frequency waves or a low-frequency wave?
High frequency waves will have more energy than low-frequency waves. This is because energy is directly proportional to frequency in waves - the higher the frequency, the higher the energy.
What are the applications of y parameters?
It may simplify your analysis especially when you are dealing with high frequency analysis...
What are the parameters of high frequency carrier that may be varied by a lower frequency intelligence?
Following are the 3 parameter by which high Frequency carrier can be varied by low frequency intelligence signal 1) Amplitude 2) Phase 3) Frequency
Why h parameter are not used for transistor mode at high frequency?
finding h parameters involves open and short circuits which is difficult to obtain at high frequencies due to stray inductance and capacitance
Difference between single parameter sensitivity and multiple parameter sensitivity?
Difference between single parameter sensitivity and multiple parameter sensitivity is that in multiple parameter sensitivity,defined parameters cannot be measured with a high degree of accuracy in the field or in the laboratory.

What does the U stand for in UHF?
Ultra high frequency.
What frequency does high energy electromagnetic have?
High energy is high frequency.
What is high frequency tuned amplifier?
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.

Is high frequency sounds low pitch?
No, high pitch means high frequency.
Does A high-pitched sound result from low frequency waves?
high pitch is high frequency, low pitch is low frequency
Effect of high frequency sounds in birds?
effect of high frequency sounds
