frequency domain or time domain. A simple frequency domain measurement involves directly counting and displaying the frequency output of the DUT with a frequency counter. The reference for this measurement is either the counter’s internal time base oscillator, or an external time base (Fig. 17.3).

tween the time and frequency domains and in fact the Fourier transform of the Fourier transform gets us back to the original signal, time-reversed. In discrete time the situation is the opposite. The Fourier series represents a pe-riodic time-domain sequence by a periodic sequence of Fourier series coeffi-cients.
