Not all emitters transmit either a continuous wave (CW) or pulsed waveform. Some emitters can transmit both CW and pulsed waveforms, depending on the design and application.

For example, certain types of radar systems may use both CW and pulsed waveforms for different purposes. CW signals can provide precise continuous measurements of velocity and range, while pulsed waveforms can be used for target detection and tracking applications.

In summary, while many emitters may be classified as transmitting either CW or pulsed waveforms, there are also emitters capable of transmitting both types of waveforms, depending on the specific requirements of the application.
