摘要：
An LPC analyser calculates LPC coefficients using signals bandlimited to half the sampling frequency of the LPC coefficients to be calculated. Thef calculated LPC coefficients are continuous in time scale and free from aliasing distortion. A bandlimiting circuit suitable for use in the LPC analyser is also disclosed.
