This lecture explains the concept of modulation in communication systems, where information signals are embedded onto carrier signals for transmission. It covers the process of modulation, transmission, and demodulation, emphasizing the importance of frequency differences. Through a detailed example, the instructor illustrates how to trace the signal in the Fourier domain, design a low pass filter, and recover the original signal. The lecture concludes by discussing the implications of carrier frequency relative to the information signal frequency.
