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.

Does high frequency correspond to high pitch?
Yes, high frequency corresponds to high pitch.
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.
