No, an echo is not an example of the Doppler effect. The Doppler effect occurs when there is a change in frequency of a wave due to the relative motion between the source of the wave and the observer. An echo is created when sound waves reflect off a surface and return to the listener, producing a repeated sound.

The Doppler Effect was named after Austrian physicist Christian Doppler, who first described it in 1842.
The change in frequency of a sound due to motion of the source is called the Doppler effect. If the source is moving towards the observer, the frequency of the sound appears higher (blueshifted), while if the source is moving away, the frequency appears lower (redshifted). This effect is commonly experienced with passing vehicles and sirens.
A bat can tell how big an insect is based on the intensity of the echo. A smaller object will reflect less of the sound wave, and so will produce a less intense echo.The­ bat can sense in which direction the insect is moving based on the pitch of the echo. If the insect is moving away from the bat, the returning echo will have a lower pitch than the original sound, while the echo from an insect moving toward the bat will have a higher pitch. This difference is due to the Doppler effect

For example, it can clearly be seen - by the Doppler effect - that the Universe is expanding.
