ABSTRACT:
Various selected characteristics of digital (or analog) signals in an electrical circuit are converted into audible signals and transmitted as a sound pattern(s) through a speaker or headphones to a user. Such selected signal characteristics include pulse width, duty cycle, activity level (state changes), repetitive pattern comparison, and sampled signal level. Some representative types of differentiable noise or sounds include clicks, pitch, harmonics, noise bursts, ticks and tocks, and voice stopped consonants. By matching selected noise types with selected characteristics an audible display is generated which represents to the user various characteristics of the sampled signal either individually or collectively.
