	Implement a speech denoising technique, which goes through the following steps: Load a speech signal from a WAVE file. Generate a white noise signal of equal duration with the speech signal. Use a highpass filter to preserve the frequencies of the noise above 3 kHz. Add the filtered noise to the original signal. Denoise the signal with a lowpass filter. Reproduce all three signals and plots their spectrograms.	1,2,4,5,8,9, 10,12	1,2
	Generate a synthetic signal that consists of three frequencies. Then, create a lowpass filter and apply it on the generated signal. Plot the spectrograms of the initial and the filtered signal, along with the frequency response of the designed filter.	1,2,4,5,8,9, 10,12	1,2
