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 ... WebThe Scala Math sin () method returns trigonometric sine of an angle (angle should be in radians). In special cases it returns the following: If the argument is NaN or an infinity, then the result is NaN. In the graph below, sin (x) vs x is plotted.
