Gradient descent based adaptive IIR filtering with direct and lattice form filter structures; applied to estimation of a headphone compensation filter and binaural head related transfer functions
… Processing (DSP), Finite Impulse Response (FIR) filters are commonly used due to their stability and ease of design. However, Infinite Impulse Response (IIR) filters offer better frequency resolution at lower filter orders, making them ideal for hardware-constrained applications like portable …
