Question

The frequency of an FM transmitter without signal input is called (A) the centre frequency (B) modulation factor (C) the frequency deviation (D) the carrier swing

Tardigrade Admin · Accepted Answer

In FM, carrier frequency is the constant frequency which is modulated by signal amplitude. It is also called carrier swing. (Centre frequency is f

_{c}

in AM wave frequency deviation

δ = f_{ma x} - f_{c},

modulation factor =

\frac{δ _{ma x}}{f _{c}})

Q. The frequency of an FM transmitter without signal input is called

the centre frequency

modulation factor

the frequency deviation

the carrier swing

In FM, carrier frequency is the constant frequency which is modulated by signal amplitude. It is also called carrier swing. (Centre frequency is fc​ in AM wave frequency deviation δ=fmax​−fc​, modulation factor = fc​δmax​​)

In FM, carrier frequency is the constant frequency which is modulated by signal amplitude. It is also called carrier swing. (Centre frequency is f $_{c}$ in AM wave frequency deviation $δ = f_{ma x} - f_{c},$
modulation factor = $\frac{δ _{ma x}}{f _{c}})$
