hi guys:(adsbygoogle = window.adsbygoogle || []).push({});

if i have signal(YT) consist of two frequencies(30 and 300 Hz),as the following:

i want remove the frequency of 300 Hz from(YT) by using low pass filterCode (Text):

t=0:1/1000:1;

Y30=sin(2*pi*t*30);

Y300=sin(2*pi*t*300);

YT=Y30+Y300;

so how can i do that(by using matlab command)?
