The frequency spectrum of an AM-modulated signal has a carrier at $1 \mathrm{MHz}$ and an upper sideband at $1.01 \mathrm{MHz}$.
(a) What is the frequency of the message signal?
(b) What is the frequency of the lower sideband?

Key Concepts

Message Signal Frequency

The message signal frequency, also known as the modulation frequency, is the frequency at which the information being transmitted oscillates. It determines the spacing of the sidebands from the carrier frequency in AM. The frequency difference between the carrier and the sidebands directly corresponds to the message signal frequency.

Amplitude Modulation

Amplitude Modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In AM, the amplitude of the carrier wave is varied in proportion to that of the message signal while the frequency remains constant. This results in the creation of additional frequency components around the carrier, known as sidebands.

Carrier Frequency

The carrier frequency is the original, unmodulated frequency of the radio wave that carries the information. In modulation schemes like AM, it serves as the reference point from which the sidebands are generated by adding and subtracting the message signal frequencies.

Sidebands

Sidebands are the frequency components that appear on either side of the carrier frequency as a result of modulation. In AM, there are typically two sidebands: the upper sideband, which is the sum of the carrier frequency and the message frequency, and the lower sideband, which is the difference between the carrier frequency and the message frequency. These sidebands contain the actual information from the message signal.
