## Gesture Signal Processing

### Interpolation

### Filtering

While studying sensors, we discovered that often a particular sensor will measure the position **x**, velocity, or acceleration of an object. However,

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
