The high-frequency response of a circuit can be determined by both raising the frequency until the midrange amplitude drops to 70.7% (which corresponds to the -3dB point, a common way to define the bandwidth of a circuit) and by measuring the rise time of a fast pulse, as the rise time can give information about the circuit's ability to handle high-frequency signals.
