WebSymPy uses mpmath in the background, which makes it possible to perform computations using arbitrary-precision arithmetic. That way, some special constants, like , , (Infinity), are treated as symbols and can be evaluated with arbitrary precision: >>> sym. pi ** 2 WebSecond, concerning the normalization, you should consider the mathematics of your problem instead of doing it 3 times. You have 3 pieces of signal, the sinusoid, the noise, the mix. The first is already normalized (between -1 and 1), the second also (hence the name normal distribution for describing the noise). So you should only normalize the ...
