  The beat time {\tau}_{fpt} associated with the energy transfer between two
coupled oscillators is dictated by the bandwidth theorem which sets a lower
bound {\tau}_{fpt}\sim 1/{\delta}{\omega}. We show, both experimentally and
theoretically, that two coupled active LRC electrical oscillators with
parity-time (PT) symmetry, bypass the lower bound imposed by the bandwidth
theorem, reducing the beat time to zero while retaining a real valued spectrum
and fixed eigenfrequency difference {\delta}{\omega}. Our results foster new
design strategies which lead to (stable) pseudo-unitary wave evolution, and may
allow for ultrafast computation, telecommunication, and signal processing.
