The female reply is much less bright, a pulsed signal during the dark period of the male.

By the end of the 19 century, pen registers were widely used to record pulsed electrical signals in many contexts.

A receiver, modified to pass pulsed signals, had its antenna mounted some distance away from the transmitter.

It uses a pulsed signal.

The original avalanche beacon was an analog beacon which transmitted the pulsed signal as an audible tone to the user.

These instruments work by sending a short pulsed signal into the cable and measuring how long the reflection takes to return.

This gives stepped output waveforms instead of pulsed signals.

Time of flight systems determine the distance by measuring the time of propagation of pulsed signals between a transmitter and receiver.

Clan awoke when his wristwatch's silent alarm sent its pulsed tingling signal up his left arm.

This system used a pulsed signal sent at a very low repetition rate to allow a single antenna to be used for both transmit and receive.
