There is a bit of an argument on the exact baseband pass frequency for telephone audio, but generally it is in the range of 300 hz to 3000 hz.
The broadcasting frequency range is from 300kHZ to 3400kHZ.
The frequency range of FM signal is 88hz to 108hz.
The signal with a frequency of 200Hz has a wider bandwidth compared to a signal with a frequency of 100Hz. Bandwidth is determined by the range of frequencies present in a signal, so a higher-frequency signal will have more frequency components and thus a wider bandwidth.
Suppose that a signal is bandlimited to the frequency range extending from f1 to f2.The process of frequency translation is one in which the orignal signal is replaced with a new signal whose specteal range extends from f1' to f2' and which new signal bears in recoverable form ,the same information as was borne by orignal signal.
Upper sideband = Carrier frequency + modulating frequencyLower sideband = Carrier frequency - modulating frequency

the frequency range of an am wave is 20herz to 20kilo herz
narrowband
Trasmitting stations have their own transmitting frequency. No one can construct an amplifier which amplifies signals over a wide range. So every transmitting frequency has to be changed to one particular frequency. This is known as INTERMEDIATE frequency (IF) This is quite possible by getting beats. So a signal is to generated whose frequency is just more than the incoming frequency by IF This signal is named as local singnal which is generated by the LOCAL oscillator.
In MATLAB, the frequency range can refer to the specific set of frequencies you want to analyze or visualize, often defined within a particular context, such as signal processing or Fourier analysis. For example, when using the Fast Fourier Transform (FFT), you can obtain the frequency range by specifying the sampling rate and the length of the signal. The frequency vector can be generated using the fft function, typically spanning from 0 to half the sampling rate (Nyquist frequency) for real-valued signals. You can create a frequency vector using the linspace or fft functions to define the desired frequency range based on your application.
Actually the amplitude depends on your modulator by which you generated your signal you can pick any amplitude you want but here is the formula for frequency modulated signal: Ac here decide the amplitude of the signal and you can see that it is not related to the frequency component of your signal.
A radio signal can travel long distances, potentially thousands of miles. The range of a radio signal is influenced by factors such as frequency, power of the transmitter, antenna height, atmospheric conditions, and obstacles in the signal path.
