directly. (b) Discuss the role of modulation in signal transmission and the methods of modulating a sinusoidal carrier. (c) Using a plot of an AM signal, Modulated Signal. ▻ Some parameter of the carrier (amplitude, frequency, phase) is varied in accordance with the baseband signal x(t) t. X(f) f. Modulator. AMPLITUDE MODULATION. ACHIEVEMENTS: modelling of an amplitude modulated (AM) signal; method of setting and measuring the depth of modulation; waveforms and. Set the signal generator to create an AM wave with a sinusoidal modulating signal with a frequency between 100 and 400 Hz. Use a 3. kHz carrier frequency. • called modulation to convert the electrical signal into a form that is suitable for Am and Ac are the amplitude of the modulating signal and the carrier In modulation, one characteristic of a signal. (generally a sinusoidal wave) known as the carrier is changed based on the information signal that we. Amplitude Modulation (AM) and its variants;. • Angle Modulation with special case - FM;. Message signal: m(t) baseband signal with bandlimited to B Hz. ForAmplitude Modulation (AM). OBJECTIVES. 1. Demonstrate an amplitude-modulated carrier in the time domain for different modulation.
