Abstract: A system and method are disclosed for performing digital multi-channel decoding of a BTSC composite audio signal. Each subsequent stage of the digital multi-channel decoding process is performed at the lowest sampling rate that yields acceptable performance for that stage. Analog-to-digital conversion of the composite audio signal is performed first to generate a composite digital audio signal. After analog-to-digital conversion, all signal processing may be performed in the digital domain. The composite digital audio signal is digitally filtered to frequency compensate for variations caused by previous stages of processing, including IF demodulation. Digital channel demodulation and filtering are performed to isolate single channels of the composite digital audio signal such as SAP, L−R, and L+R channels. SAP and L−R channels are DBX decoded resulting in corresponding decoded signals using a unique combination of digital filters that are an efficient translation of a corresponding combination of analog filters. The decoded L−R channel and the L+R channel are re-matrixed to form left and right stereo signals. Any of the SAP signal, left and right stereo signals, and L+R channel signal may be sample rate converted and output at a standard audio output rate.

Abstract: A system and method are used to perform division or complex division using multiplication and/or summation devices and steps. A numerator and denominator of a complex division signal are filtered. A separate determination of their values is performed using separate logic systems. The separate values are multiplied together for form an output signal. The denominator logic system converts the complex division signal into a signal that is processed using multiplication and summation devices. The processing adjusts an approximated past value using an error value. The error value can be based on a present value, a past value, and a scaling coefficient.
