Introduction to theory and practice of signals and systems engineering in continuous and discrete time. Hands-on experience with representative engineering tasks in laboratory sessions involving audio, images, and other signals. Time-domain concepts: energy, power, periodicity, fi ltering, linear system, convolution, correlation, detection, modulation, sampling, quantization, histogram. Frequency-domain concepts: sinusoids, exponentials, Fourier series, Fourier transform, frequency response. Digital processing of analog signals.
