Methods and Devices for Input Signal Conversion Simulation

A method for simulating and optimizing an analog to digital converter comprising:

• receiving, by a virtual analog digital converter (VADC), a representation of an analog signal from a first device;
• applying a filter to the representation of the analog signal;
• determining a sample timing uncertainty of the VADC;
• determining, for the representation of the analog signal, a first amplitude correction amount based on the sample timing uncertainty of the VADC;
• applying the first amplitude correction amount to the representation of the analog signal;
• sampling the representation of the analog signal at a predetermined sampling rate, to obtain a plurality of digital samples, each sample having an amplitude;
• determining an effective number of bits (ENoBDC) of the VADC based on a noise associated with the VADC and a hardware bit architecture of the VADC, wherein the noise is related to a bandwidth of the VADC;
• determining, for each digital sample, a second amplitude correction amount according to the ENoBDC of the VADC;
• applying the second amplitude correction amount to the plurality of digital samples;
• outputting, by the VADC, the plurality of digital samples as a representation of a digital signal.
