Linear predictive vocoders use __________ to estimate present sample.(

1.	Linear predictive vocoders use __________ to estimate present sample.(a) Weighted sum of past samples(b) Multiplication of past samples(c) One past sample(d) Do not use past samplesThis question was addressed to me in an interview for job.This question is from Linear Predictive Coders topic in division Speech Coding of Wireless/Mobile
Answer» The CORRECT answer is (a) Weighted sum of PAST samples To EXPLAIN: The linear predictive coder USES a weighted sum of p past samples. Using this technique, the current sample can be WRITTEN as linear sum of the immediately precoding samples.
