<p><b>Halaman baru</b></p><div>'''''' () adalah ukuran yang digunakan dalam bidang [[sains|ilmiah]] dan [[keteknikan|rekayasa]] yang membandingkan level [[Sinyal (elektrik)|sinyal]] yang diinginkan terhadap [[:en:noise (signal processing)|derau]]. Nisbah ini ditakrifkan sebagai nisbah antara sinyal dan derau yang menggunakan satuan daya, dan terkadang diekspresikan secara [[desibel]]. Nisbah yang melebihi 1:1, atau lebih dari 0 dB, mengindikasikan bahwa sinyal yang diinginkan lebih banyak dibandingkan derau.<br />
<br />
==Pengurangan derau==<br />
<br />
<br />
Seluruh hasil pengukuran menggunakan perangkat elektronik selalu menghasilkan derau. Derau dapat muncul secara internal ([[Derau (elektronika)|derau elektronik]]) tapi bisa juga karena faktor eksternal seperti angin, kelembapan, getaran, variasi temperatur, hingga variasi gravitasi akibat fase bulan, tergantung jenis alat ukur elektronik yang digunakan dan sensitivitasnya. Mengurangi derau dengan mengatur kondisi lingkungan dapat dilakukan. Sedangkan untuk mengurangi derau elektronik internal dapat digunakan [[penguat rendah derau]].<br />
<br />
Ketika karakteristik dari derau diketahui dan bentuknya dapat dibedakan dengan sinyal yang diinginkan, maka sangat mungkin untuk menggunakan filter untuk mengurangi derau. Jika sinyal yang diinginkan bersifat konstan atau periodik tetapi derau bersifat acak, derau dapat dikurangi dengan melakukan [[perataan sinyal]] hasil pengukuran.<br />
