The bitwise complement operator is a unary operator (works on only one operand). It takes one number and inverts all bits of it. When bitwise operator is applied on bits then, all the 1’s become 0’s and vice versa. The operator for the bitwise complement is ~ (Tilde). Web14.7.1 Hard Thresholding. To suppress the noise we apply the following nonlinear transform to the empirical wavelet coefficients: , where is a certain threshold. The choice of the threshold is a very delicate and important statistical problem. On the one hand, a big threshold leads to a large bias of the estimator. b. is for bug
