Detailed Description
Second-order IIR filter in Direct Form I. Maintains separate input and output histories (x and y delay lines). Requires more memory than DF2 but is less susceptible to quantization issues with fixed-point arithmetic.

Member Function Documentation
◆ process()
Processes the input value and returns the filtered output value.
Implements Filter< T >.
◆ reset()
Clears the internal state (delay lines) without changing the coefficients. Call after reconfiguring filter parameters via begin() to avoid transients from stale state.
Reimplemented from Filter< T >.
