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.
