## What is frequency sensitivity?

The dependence of the critical amplitude of the signal upon its frequency and a resonance between the intrinsic oscillations of a neuron and the signal could account for the frequency sensitivity.

## What is frequency sensitivity formula?

Frequency sensitivity, kf=40Hz/volt. We know the formula for Frequency deviation as.

## What is frequency deviation in FM?

) is used in FM radio to describe the difference between the minimum and maximum extent of a frequency modulated signal, and the nominal center or carrier frequency.

## What is frequency deviation formula?

Frequency deviation is used in FM radio to represent the maximum difference between an FM modulated frequency and the nominal vector frequency. Δf denotes it. The formula for frequency deviation is given as: Δf = kfx(t)

## What are the advantages of frequency modulation?

The main advantages of FM over AM are:

• Improved signal to noise ratio (about 25dB) w.r.t. to man made interference.
• Smaller geographical interference between neighboring stations.
• Less radiated power.
• Well defined service areas for given transmitter power.
