Intuitively, noise has violent fluctuations, i.e., its frequency spectrum occurs in the high-frequency region. Removing high-frequency components from a function results in a smooth function with less noise. 1.2 Approximation Changing an analog signal to a discrete signal is called discretization. ...
an analog signal can be used as input for a computer by using an adc or “analog-to-digital converter”. this device takes an analog signal as input and converts it into a digital one which can then be read by the computer’s cpu or gpu chips for further processing. what are some ...

the design of the analog portions of a mixed-signal circuit often uses unique cells that do not readily lend themselves to design automation and may produce unpredictable and often harmful interactions with the digital circuitry. Substrate noise, instability, and temperature drift are factors that oft...

A mathematical analysis was made on the bistable stochastic resonance model with small system parameters. An analogue circuit was designed to perform the effect. The effect of signal modulating noise was shown in the analog simulation experiment. The analog experiment was conducted for two sinusoidal ...
with activated low-pass-filter limiting the measurements to 25 MHz. The tool exhibited a small DC-offset of 2 mV, which was corrected in Figs.3and4. To improve the readability of the graphs, noise has been reduced by a running average filter, which also slightly reduced the signal ...

nodes are hard to incorporate efficient optical nonlinearity1,6. Moreover, previous ONNs may be sensitive to noise at a low signal-to-noise ratio (SNR)8,28,35, making them vulnerable to shot-noise fluctuations because of ultra-short exposure time. These issues notably prevent existing photonic...
