The frequency of sound emitted by a continuous wave probe is _____ the frequency of the electrical signal.

Explanation:
The emitted sound frequency matches the driving electrical signal because the transducer converts that electrical tone directly into mechanical vibrations at the same rate. In continuous wave ultrasound, you send a steady tone; there’s no modulation or pulsing that would shift the frequency, so the sound frequency is equal to the electrical drive frequency. The Doppler effect can alter the frequency of echoes returning from moving tissue, but it changes the received signal, not the transmitted frequency. Therefore, the correct relationship is equality.
