| + | * Met with Andy and Daisy | ||
| + | * Implemented FIR LP third order filter with uniform weights with real time processing | ||
| + | * Results did not come out as expected - signal not rectified | ||
| + | * need to consider other FIR LPF designs (orders and coefficient weights) | ||
| * To Do: | * To Do: | ||
| + | * Implement other filtering methods and compare their accuracy and responsiveness to abrupt changes | ||
| + | * Implement different frequency domain analysis methods to extract any useful information between indoor conditions and outdoor ambient noise | ||
