The DF1 IIR filter structure is the most common structure employed in audio applications. A limiting factor associated with the DF1 structure is the non-linear distribution of the pole/zero locations in the `z` domain after coefficient quantization. This paper proposes the application of dither to double precision coefficients which permits double precision performance to be achieved with single precision arithmetic. This realization provides a versatile wide band DF1 realization suitable for most audio applications.
