Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

A data-determined method for testing structural models of the errors in vector autoregressions is discussed. The method can easily be combined with prior economic knowledge and a subjective analysis ...

This course covers various continuous voltage/current time functions and their applications to linear time-invariant (LTI) electrical systems. It reviews pertinent topics from previous courses on ...
