Aim: To build a low cost portable device to detect fetal heart rate using an array of ECG electrodes and
ADS128
- Data Acquisition: Developed a Python based algorithm for data extraction and real time noise cancellation for abdominal ECG data
- Data Cleaning: Implemented filtering techniques in MATLAB to remove maternal ECG and motion artifacts from the raw data
- Detection: Developed the MATLAB based algorithms for detecting fetal RR peaks from abdominal signals.
MATLAB based Voice Command Recognition System
- Linear Prediction: Implemented Linear Predictive Coding in MATLAB. Implemented a MATLAB based detector
to detect formant peaks in given speech phrases.
- Command recognition: Used LMS Filtering, MFCC-DTW coecients to detect and execute
5 voice commands from recorded speech signal
