| Summary: | This paper presents a proposal of a new way to generate analog noise, discrete in time,
with uniform probability density function. Instead of the usual way of generating discrete
analog uniform noise using a uniform pseudorandom number generator and a digital-to-analog
converter, generating based on non-equidistant sampling of sawtooth voltage is suggested.
The original hardware structure that implements this idea is suggested and its work is
simulated. The simulations have confirmed the validity of the idea. The main gain is
the unlimited resolution of the analog output of the uniform noise generator suggested.
The resolution of standard uniform noise generators is limited by the resolution of
the digital-to-analog converter used. |
