6.003 covers the fundamentals of signal and also system analysis, concentrating in representations of discrete-time and additionally continuous-time signals (singularity features, complex exponentials as well as geometrics, Fourier representations, Laplace as well as Z transforms, sampling) as well as representations of linear, time-invariant techniques (difference and additionally differential equations, block diagrams, system functions, poles and zeros, convolution, impulse and also option responses, frequency responses).
