Fungsi jendela $w(n)$ berfungsi untuk melokalisasi sinyal dalam domain waktu, dengan meruncingkan sinyal di kedua ujungnya guna meminimalkan diskontinuitas. Hal ini sangat penting untuk mengurangi **kebocoran spektral**—sebuah fenomena di mana energi sinyal menyebar ke bin frekuensi di sekitarnya akibat pemotongan sinyal secara tiba-tiba. Pemilihan jenis jendela sangat memengaruhi resolusi dan akurasi representasi waktu-frekuensi.
