In this case the noise's band is theoretically infinite, but for our purposes it will suffice to consider the frequency segment that we're most interested in, namely, our usual theoretical audible frequency spectrum: 20Hz - 20KHz.

The aim is to memorize information which will in some way represent the sound wave-form and will allow it to be reproduced successively. To fix our ideas, let's suppose that the wave we need to memorize is once again, our friend the sinusoid wave, always bearing in mind the fact that our example can be quite effortlessly be expanded to more complex wave-forms.

Electronics history has been marked by the introduction of components that have opened the doors to new solutions and technology. The real revolution took place with the transistor, preceded by the diode, which marked the definitive birth of digital electronics, leading to the introduction of microprocessors.
