    I/Q data and envelope

    Hi,

    How to understand this statement:

    The digital processing computes the root sum of the squares of the I and Q data, which is mathematically equivalent to an envelope detector?

    Does it mean sqrt(I2 + Q2) only has the envelope?

    Senmeis

    I agree. Why "only" enevlope? It's a scalar quantity, it can't hold more than one information.

    Re: I/Q data and envelope

    I think the most important characteristic is, the swings between envelopes must disappear. Can this operation support this?

    Basic trigonometric relation sin²x + cos²x = 1
