In the long-term and short-term linear prediction model for speech production, the long-term predictor has a delay of T, while the short-term predictor has an order of M, with T > M. Is it functionally equivalent to replace the cascade connection of pitch synthesis filter and formant synthesis filter with a single filter composed of a predictor of order T with system function
