To reduce noise in a signal by applying a moving average filter in MATLAB, you can use the movmean()
function. The movmean()
function computes the moving average of a vector, with a specified window size. Here's an example code to apply a 5-by-5 moving average filter to a noisy signal:
main.m297 chars13 lines
In the above code, t
is a vector containing time samples, and x
is the noisy signal. The movmean()
function is used to compute a moving average of x
with a window size of 5 samples. The resulting filtered signal is stored in y
. Finally, the plots of original and filtered signals are displayed using the plot()
function.
