Noise Reduction with IIR Butterworth Filter
The desired frequency is 1kHz and 1.7kHz.
It is added with White Gaussian Noise.
The noisy Signal is being filtered with Bandpass, and then Bandstop.
Both of the Filters and design with Butterworth 2nd order, it be better by increasing the order.
Feel free to experiment it, you may also insert your own signals.
