Most of today's DSP µPs, which are offspring of standard µPs, operate in the time domain. However, frequency-domain operation provides benefits for a whole spectrum of applications. Ever-increasing ...

There is no such thing as a “frequency domain” — there is only dv/dt. This artificial notion was born in 1807, when mathematician Joseph Fourier announced to the French Academy a discovery so ...

Fig 1. The Tektronix MDO4000 enables designers, for the first time, to capture time-correlated analogue, digital, and RF signals for a complete system view of their device. Fig 2. The spectrum shown ...
