## Survey of Methods to Compute Linear Convolution

Mathematical details of convolution, its relationship to polynomial multiplication and the application of Toeplitz matrices in computing linear convolution are discussed in the previous article. A short survey of different…

## Sampling Theorem – Baseband Sampling

For Matlab demo of sampling see here. “Nyquist-Shannon Sampling Theorem” is the fundamental base over which all the digital processing techniques are built. Processing a signal in digital domain…

## Correlative coding – Duobinary Signaling

The condition for zero ISI (Inter Symbol Interference) is $$p(nT)=\left\{\begin{matrix} 1,\; n=0\\ 0,\; n\neq 0 \end{matrix} \right.$$ which states that when sampling a particular symbol (at time instant…
