專利摘要：
The present invention discloses an envelope detection circuit by using a peel cone approximation concept. The envelope detection circuit comprises an absolute value comparision mechanism, a read only memory and a multiplier/adder mechanism. Particularly, the present invention uses a divider to generate an address of the read only memory to obtain less error and less hardware cost.
