Digital Signal Processing
In Matlab command, load the data file "KTXSignal'. Check the data variable. The sampling rate of the sisgnal is 100/sec.
>> load KTXSignal
>> load KTXSignalWithNoise
1. Plot 'KTXSignal' along the actual time axis 't'.
>> plot(t, signal)
Ts = 0.01
t = 0 : Ts : 0.99 % 0초부터 0.01초간격으로 0.99초까지의 KTXSignal
plot (t, KTXSignal) % KTXSignal을 보여줌
2. Plot 'KTXSignalWithNoise' along the actual time axis 't'.
>>plot(t,KTXSignalWithNoise)
Ts = 0.01
t = 0 : Ts : 0.99 % 0초부터 0.01초간격으로 0.99초까지
plot (t, KTXSignalWithNoise) % KTXSignalWithNoise을 보여줌
3. We want to remove the noise from 'SigWithNoise' by an average filter . We denote the filtered signal as . For an example, when L=10, in Matlab
>>L=10;
>>h=ones(1,L)/L;
>>y=conv(h,KTXSignalWithNoise);
1) Check for the length of y[n]. Let p be the length of y[n]. Determine the length of y[n] in terms of L and M=length(SigWithNoise).
