Background Information is Reviewed

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

Hilbert Transform and Fourier Transform of Hilbert Transform

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

Pre-Envelope and Complex Envelope of Analog Signals

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 and Demodulation

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.

Single Sideband Amplitude Modulation (SSB-AM Modulation)

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 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.

Superheterodyne Receiver
