Do an inverse DFT of that and this results to a sinc pulse. Use that sinc to filter your data. The longer the sinc, the sharper the cut off. grasshopper graphic statics

"A high-pass filter (HPF) is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. The amount of attenuation for each frequency depends on the filter design. A high-pass filter is usually modeled as a linear time-invariant system. It is sometimes called a low-cut filter or bass-cut filter in the … " - High pass gravity filter algorithm
