A 6 dB division and intuitively the half, 3dB, have definitely a
meaning.
6dB equals a doubling in voltage and a four times the power, 3dB
increase a power doubling, and so on.
Everything loses meaning when the AGC voltage doesn't follow this
logaritmic law and a receiver is a communication equipment rather than
an instrument.
