Here is a Matlab demonstration using Simulink on synchronous detection. Synchronous detection is used to demodulate Double Sideband Suppressed Carrier AM (DSB-SC AM). Also known as coherent or homodyne detection, the scheme requires phase information to track the phase drift of the transmitted carrier in order for this detection scheme to work. A basic component used to achieve this detection scheme is a phase-locked loop (PLL) circuit. The PLL circuit is more complicated than the envelope det… Continue

Here is an example using Matlab's Simulink to demonstrate the concept of Amplitude Modulation. Two types of amplitude modulation schemes are discussed: Double Sideband Suppressed Carrier (DSB-SC) AM and Double Sideband Large Carrier (DSB-LC) AM. DSB-LC AM is used your standard and commercial AM radio. Continue

You can view the convolution as the inverse z-Transform of Y(z)=H(z)U(z) where Y(z), H(z), and U(z) are the Laplace Transform of the output sequence response, impulse system response, and input sequence, respectively. DVDs are in progress and are based on market demand on selected topics. Part 1 - Introduction This is an introduction to the convolution sum before giving you an example in Part 2. Continue
