Amplitude Modulation (A.M)
- A modulation technique where the amplitude of the carrier signal is varied in proportion to the amplitude of the modulating signal.
- The modulating signal typically contains information, such as voice or data.
Percent Modulation in AM
- A measure of the degree to which the carrier amplitude is varied.
- Calculated as: `Percent Modulation = (Amplitude of Sidebands) / (Amplitude of Carrier) x 100`
Pilot Carrier
- A low-level, unmodulated carrier signal transmitted along with the modulated signal.
- Used to align the demodulator in the receiver and ensure that the carrier frequency is adjusted accurately.
