Abstract

Penelitian ini bertujuan untuk mensimulasikan filter digital Finite Impulse Response (FIR) menggunakan metode windowing untuk menghilangkan noise pada sinyal suara. Filter FIR dipilih karena kemampuannya dalam memberikan stabilitas dan linearitas fase yang penting dalam pemrosesan sinyal digital. Beberapa metode windowing digunakan untuk merancang filter dengan karakteristik berbeda dalam hal peredaman noise dan respon frekuensi. Simulasi dilakukan menggunakan MATLAB untuk menguji efektivitas masing-masing metode windowing dalam mengurangi noise pada sinyal suara. Hasil penelitian menunjukkan bahwa Window Kaiser memberikan hasil terbaik pada noise 0,25 dBW dengan menghasilkan nilai Signal-to-Noise Ratio (SNR) sebesar 26,6632 dB. Pada level noise 0,5 dBW Window Kaiser menunjukkan performa terbaik dengan menghasilkan Signal-to-Noise Ratio (SNR) sebesar 13,4842 dB. Dilevel noise 0,75 dBW menunjukan jika metode Window Kaiser menghasilkan Signal-to-Noise Ratio (SNR) tertinggi sebesar 5,9239. Pada penelitian ini Window Rectangular mendapatkan hasil paling rendah dari ke-3 level noise. Dengan menggunakan filter FIR berbasis windowing, peningkatan kualitas audio dalam berbagai aplikasi seperti telekomunikasi dan multimedia telah terbukti. Filter FIR mampu menghilangkan noise tanpa mengorbankan komponen sinyal yang diinginkan, yang penting untuk aplikasi komunikasi yang memerlukan kejelasan audio yang tinggi.

Abstract

Several years ago, perhaps there were still many people who did not know Kertarahayu Village, located in Setu District, Bekasi Regency, West Java. However, thanks to the hard efforts & struggles of all regional apparatus and elements of society in Kertarahayu Village, finally this village began to sound echo and also succeeded in developing several important places into tourist attractions as well as valuable assets for Kertarahayu Village. This also encourages a lot of appreciation that comes from the Regional Apparatus, especially in Setu Subdistrict and Bekasi Regency. When the Bekasi Regent visited Kertarahayu Village as part of the Gebyar Desa event, they all gave feedback regarding the condition of Kertarahayu Village and also related to the activities carried out to realize the existence of Kertarahayu as one of the best tourist villages in Bekasi Regency. Don't forget to convey hope for Kertarahayu Village. In addition, there are also aspirations that come from the village community which describes infrastructure development & also the condition of tourism in this area
