Lecture
This lecture covers the concept of instantaneous frequency in signals and systems, focusing on angle modulation practical considerations such as carrier pulsation, phase sensitivity factor, and frequency deviation. It also discusses frequency modulation, bandwidth determination, and modulation types like pulse amplitude modulation (PAM). The presentation delves into the analysis of FM and PM signals, essential bandwidth calculation, and modulation complexity. Additionally, it explores advantages of angle modulation over amplitude modulation, digital data transmission techniques, and noise resistance. The lecture concludes with a detailed examination of sample and hold operations, frequency analysis, and reconstruction conditions for PAM and SH-PAM.
