Background Information is Reviewed

In this lecture, we provide background information for analog communication subjects.

In this lecture, we give the definition of Hilbert transform and derive its Fourier transform and solve some exercises related to Hilbert transform.

In this lecture, we explain Pre-Envelope and Complex Envelope of Analog Signals.

In this lecture, we further give information about the complex envelope of a bandpass signal, and derive mathematical relations between complex envelope of a bandpass signal and bandpass signal itself. Besides, we derive the convolution relation between the complex envelopes of a bandpass system.

Amplitude Modulation is explained and the meaning of modulation is clearified.

In this lecture, double sideband amplitude modulated signal is inspected in frequency domain, and envelope detector for the demodulation of the DSB-AM signal is analyzed.

In this lecture, we explain double-sideband suppressed-carrier amplitude-modulation.

In this lecture, we continue solving examples about amplitude modulation, and calculate the Fourier transform of DSB-SC AM

In this lecture we explain ring modulator which is used for the generation of DSB-AC AM signals.

In this lecture, we explain demodulation of DSB-SC AM signals. Different demodulation structures such as 'coherent demodulator', 'costas loop', 'squaring loop' are explained. We also explain QAM modulator and demodulator.

In this lecture, we explain single sideband amplitude modulation. We derive time and frequency domain expressions for USSB-AM signals.

In this lecture, we explain the generation of lower single sideband amplitude modulated (LSSB-AM) signals. We also give information about the demodulation of LSSB-AM signals.

In this lecture, we explain vestigial sideband amplitude modulation, which is used for the transmission of TV signals.

In this lecture, we explain the phase and frequency modulation methods in time domain.

In this lecture, we continue explaining phase and frequency modulation methods.

In this lecture, we explain the narrowband/wideband FM and PM signals. We derive mathematical expressions for narrowband FM and PM signals.

In this lecture, we explain the Carson's rule used to calculate the bandwidth of wideband FM signals.

Bandwidth of Frequency Modulated Sinusoidal Signal is continued from the previous lecture, Bessel Function and Radio Spectrum are explained.

In this lecture, we explain the working principles of narrowband FM generator circuits.

In this lecture, we explain the generation of wideband FM signals.

In this lecture, we explain how to demodulate the FM signals using frequency discriminator circuits.

Limiter devices are used to smooth the time varying cosine signals. Limiter are used to alleviate the time varying nature of NBFM signals, and they are also used in front of the FM demodulators. In this lecture, we explain the limiters and the places they are used.

We explain the Superheterodyne Receiver used by FM / AM radio, TV receivers.

We explain the Superheterodyne Receiver further. Image frequency is explained.

Reviews summary

In-depth analog communication theory

According to learners, this course offers an exceptional theoretical depth into Analog Communication, making it ideal for those seeking a strong foundational understanding. Students frequently praise the comprehensive coverage of modulation and demodulation techniques, including advanced topics, and find the mathematical derivations explained thoroughly. However, some learners note that the pacing can be quite fast and that the course assumes a solid background in signal processing, potentially making it challenging for beginners. There's also a common sentiment for more practical examples and simulation exercises to complement the highly theoretical approach. Recent reviews suggest improved clarity in explanations, indicating instructor responsiveness.

Newer reviews indicate enhanced clarity in instructor's explanations.

"The instructor's clear explanations on complex concepts make this course a gem for engineers."

"The instructor seems to have improved the clarity of explanations in recent updates, which was a great help."

"While older reviews mentioned lectures were just derivations, recent ones show a noticeable improvement in presentation quality."

Covers a wide range of essential analog modulation techniques.

"I appreciate the comprehensive coverage of modulation techniques, including advanced topics like VSB-AM."

"The section on Superheterodyne Receiver was particularly useful and clearly explained."

"I liked the detailed breakdown of different modulation schemes, including DSB-AM, DSB-SC AM, SSB-AM, and VSB-AM."

Provides a strong, detailed theoretical foundation in analog communication.

"Excellent course for a deep dive into analog communication. The mathematical derivations are explained thoroughly, which really helps solidify understanding."

"This course is fantastic for anyone looking to understand the underlying principles of analog communication. The instructor goes into great detail, far beyond what many textbooks cover."

"Truly an exhaustive treatment of analog communication. I especially valued the coverage of Carson's Rule and Bessel functions in relation to FM signals."

Predominantly theoretical, with limited practical examples or labs.

"I wish there were more practical examples or simulation exercises to complement the theory, as it felt very academic."

"It's a good theoretical course, but don't expect much hands-on application; it's mostly derivations on a whiteboard."

"I think it could be even better with some companion lab exercises or more real-world examples to illustrate the concepts."

Course pacing is fast and assumes significant prior technical knowledge.

"The pacing can be quite fast if you're not already familiar with signal processing; some explanations could be more intuitive."

"Absolutely not for beginners. The course assumes you know everything already. No clear explanations of basic concepts, just jumps into complex math."

"The content requires a solid background in calculus and transforms, which might be a hurdle for some learners without prior exposure."
