Describe what frequency modulation (FM) means.
A sinusoidal carrier wave possesses a frequency of $600\,\text{kHz}$ and an amplitude of $5.0\,\text{V}$. A sinusoidal wave of frequency $7.0\,\text{kHz}$ and amplitude $2.0\,\text{V}$ is used to frequency modulate the carrier wave. The frequency deviation of the carrier wave is $20\,\text{kHz V}^{-1}$. Determine, for the modulated carrier wave, the amplitude.
Determine the maximum frequency of the modulated carrier wave.
Determine the minimum frequency of the modulated carrier wave.
Determine the number of times per second that the frequency falls from maximum to minimum and then returns to maximum.
A sinusoidal carrier wave has a frequency of $600\,\text{kHz}$ and an amplitude of $5.0\,\text{V}$. A sinusoidal wave with frequency $7.0\,\text{kHz}$ and amplitude $2.0\,\text{V}$ frequency modulates the carrier wave. The frequency deviation of the carrier wave is $20\,\text{kHz V}^{-1}$. Determine, for the modulated carrier wave, the quantities in parts (i) to (iv).
