A new method of ultrasonic frequency analysis is introduced which employs frequency‐tracked gated rf drive pulses rather than shock‐excited broadband spikes to generate the ultrasonic waveform. The new technique, a variation of the sampled‐continuous wave technique, eliminates problems associated with finite pulse widths of conventional methods. It is shown to yield correct ultrasonic wave velocity measurements of the sample irrespective of receiver gate width or position provided any portions of two successive echoes are gated simultaneously into the spectrum analyzer. The experimental observations are substantiated by a theoretical model based on the time‐frequency domain formulation of ultrasonic frequency analysis.
