Aproximación FIR de un filtro ideal - Video

Tutorial Description
Es posible aproximar un filtro ideal, por medio de un sistema FIR. Se deben tomar muestras de la función de filtrado ideal en el dominio del tiempo en el rango [-M,M]. Al final se aplica algún enventanado para reducir las oscilaciones del espectro.

Fourier Series of A Square Wave (Version 1) - Video

Tutorial Description
Reference: freedomuniversity.ning.com The video uses Simulink within Matlab. The signal generators. Each signal generator (sine wave) is adjusted in frequency and amplitude (using the calculated Fourier Coefficients) to generate square waves. Students can try other Fourier coefficients for other type of waveforms or signal functions.
