ppg

ppg preprocessing (e.g., ppg> spectogram, bandpass, moving average)

ALL in One: Simple PPG preprocessing

Usage

Installation

pip install ppg-pre

python usage

from ppg_pre import get_ppg_sample
x = get_ppg_sample() # get sample ppg data

from ppg_pre import ppg2specgram
x = ppg2specgram(x) # u can get the spectrogram data

Function

ppg2specgram function has the following processing.

• interpolate
• bandpass (0.5~10 Hz)
• moving average (30 taps)
• z-score normalization (mean:47, std:15)
• spectrogram

Visualization

from matplotlib import pyplot as plt
from ppg_pre import get_ppg_sample

x = get_ppg_sample()
plt.plot(x[12000:15000])
