When measuring the transfer and properties of many electronic circuits it is necessary to use a measuring signal with noise of defined properties. In the paper, the design and software implementation are described of a generator of pseudorandom binary noise signal of adjustable length and with repetition of pseudorandom binary signal sequence. The parameters of noise outputs are stable, well defined...
A well-known problem in sigma-delta (SigmaDelta) modulators is limit cycle oscillations, which can cause unwanted tones of significant power to appear in the quantization error. This problem becomes more severe as the amplitude of an input signal is small. The unwanted tones can be eliminated from the quantization error by employing a properly chosen random sequence to break up the limit cycle oscillations...
