When a bird sings to attract a mating partner, competing against other birds, does it not sing for aesthetics?
Also, couldn’t harmonics be used to improve decoding in noisy environments? Spreading the signal over a wide band is not unheard of in man-made electromagnetic communication either.
- darig 5y agoSignal strength is the aesthetic. If you were a bird, you'd spend so much time trying to change what you were that you'd forget to eat your worms and die.
- karmakaze 5y agoWhen using spread-spectrum transmission it would be counterproductive to utilize harmonics. Non-sinusoidal noise at frequency F would pollute frequencies k*F. Also the transmission band is likely less than an octave.
