## Data Preparation



T: 100 sec
fs: 1000 hz

- 8 src:
- s0: 0-signal + peak *
- s1: 8 hz sine + gaussian noise
- s2: 25 hz sine + gaussian noise
- s3: uniform \[-1, 1\]
- s4: 64 hz sine * 5 hz cosine
- s5: square low-dense
- s6: cos(400t+sin(90t))
- s7: square hign-dense
- \*peak: 0-0.5 sec of 5 * sin(2 pi t)
