The frequency of remote controls for the television varies from brand to brand. The ones that do operate using radio frequencies though are all generally low frequencies. Most remote controls today operate using infrared light signals though.

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.
The delta f over f parameter in frequency modulation is significant because it represents the frequency deviation relative to the carrier frequency. It determines the amount by which the frequency of the modulated signal varies from the original carrier frequency. This parameter is crucial in determining the bandwidth and quality of the modulated signal in frequency modulation systems.

Hybrid Parameters are the values which is used to find FREQUENCY RESPONSE of a low frequency transistors. you may have doubt like why we are using only H-PARAMETERS why not HYBRID-PI models because..., h-parameters values are constant at low frequency moreover, at low frequency transition model we have assumed that the response of transistor to changes of input current or input voltage is instantaneous this is the reason why we had neglected shunt capacitances . as there were no shunt capacitances there is no chance of using hybrid-pi model. i hope you got answer for your question
It simply tells how often a particular event or parameter occurs. Save

The paging ID on a GSM network will mainly be on a radio frequency parameter. This is what allows the paging request message to have more than one MS identification.Ê
Center frequency refers to the frequency at the midpoint between the upper and lower limits of a bandpass filter or a communication channel. It is a critical parameter in signal processing, telecommunications, and radio frequency engineering as it represents the frequency around which most of the signal energy is concentrated.
