Isi artikel

Discrete cosine transform (DCT) that has been used commonly in lousy data compression, can also be used in signal filtering. Basically, this kind of filtering performed by compressing the signal using DCT up to certain level, and by decompressing that compressed signal using Inverse Discrete Cosine Transform (IDCT). The decompression result can show a filtered signal in this paper will be shown that a DCT based filter has ability to filter filtered random noise that contaminated in a signal.
