Suppose that a sinusoidal interference has been added to desirable music that has frequency components ranging from    15-Hz to 20  KHz. The frequency of the interference slowly varies in the range of 0.950 kHz to 0.990 kHz. A filter that attenuates the interference by at least 20dB and passes most of the audio components is desired. Hint: Draw a sketch of the x-axis showing all the frequency components on the x-axis
