Gesture Signal Processing
Interpolation
Filtering
While studying sensors, we discovered that often a particular sensor will measure the position x, velocity v, or acceleration a of an object. However, we might like to use a different variable to control the way we synthesize sound. Ideally, integration and differentiation can be applied to convert between variables.
Simple integrator:
y[n] = 0.1*x[n] + 0.9*y[n-1]
example of lp filter
Simple differentiator:
y[n] = x[n] - x[n-1]
example of hp filter
