HEARING OVERCOMES UNCERTAINTY RELATION AND MEASURES DURATION OF ULTRASHORT PULSES

The acoustic pressure of such a signal is p(t) = p sub(0)exp(-t super(2)/2( Delta t) super( 2))cos(2[pi] [functionof] sub(1)t), where [functionof] sub(1) is the underlying frequency. The spectrum of the signal is also Gaussian, p([functionof]) = p sub(0)exp(-([functionof]-[functionof] sub(1)) super(...

Zusammenfassung:The acoustic pressure of such a signal is p(t) = p sub(0)exp(-t super(2)/2( Delta t) super( 2))cos(2[pi] [functionof] sub(1)t), where [functionof] sub(1) is the underlying frequency. The spectrum of the signal is also Gaussian, p([functionof]) = p sub(0)exp(-([functionof]-[functionof] sub(1)) super(2)/2( Delta [ function of]) super(2)) and the widths of the two Gaussian functions are inversely proportional to one another.
