Analysis Of The Effect Filter Order Number On Noise Canceller System Using STM32F4

Communication plays an important role in society. This can be seen the amount of information that is spread, such as form sound, images, and videos. But communicating not always easy. Due to large number sounds emitted from different sources, other will disturbed. The interference caused by noise distort signal, leading a sine wave integrate minor signal. As result, receiver cannot differentiate actual signal added noise. study proposed noise-reduction system analyzing effect filter orders on canceler system. processed using STM32F4 canceller system, which then filtered adaptive with Finite Impulse Response (FIR) structure Least Mean Square (LMS) algorithm. test results show best SNR value obtained at Order 40 5.3671 dB sound duration 14 seconds, while PSNR 21.3557 9 higher order value, smaller MSE value.
