SUMMARY
The discussion centers on the Fourier Transform of a low pass filter with a bandwidth of W Hz, where the cutoff frequency fc is significantly greater than W. The proposed representation of the filter's frequency response is a rectangular function, specifically described as rect(f/W), indicating a flat response between -W and W. This confirms that the low pass filter effectively allows frequencies within this range to pass while attenuating others outside this bandwidth.
