ABSTRACT:
Systems and methods for resizing a signal for use with a fixed-point DSP are provided. More specifically, a process called companding is used in conjunction with fixed-point devices to resize a signal to make use of the available range of these devices. In some embodiments, companding is used to improve the signal-to-noise and distortion ratio. Also, information loss associated with quantization and rounding errors can be reduced in some embodiments.
