A fundamental limitation of spark-gap transmitters is that they generate a series of brief transient pulses of radio waves called damped waves; they...

mile away (counting from the leading edge of the transmitter pulse (T0), (sometimes known as transmitter main bang)). For convenience, these figures may...

A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned...

to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving...

In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic...

of 300 or 500 pulses per second. A related measure is the pulse width, the amount of time the transmitter is turned on during each pulse. After producing...

root mean square (rms) value of the pulse amplitude. In radar, the pulse duration is the time the radar's transmitter is energized during each cycle.  This...

phase of the received signals within each pulse that was used to determine the transit time from transmitter to receiver. Using hyperbolic geometry and...

an additional pulse transmitter in the top of the mast. The combination of high power pulse radar and a very low power LPI transmitter is very effective...

the basic concept, this section will consider the pulse method only. Consider two radio transmitters located at a distance of 300 kilometers (190 mi) from...

systems put about 70% to 90% of the transmitters power into the sync pulses. The remainder of the transmitter's power goes into transmitting the video's...

A universal asynchronous receiver-transmitter (UART /ˈjuːɑːrt/) is a peripheral device for asynchronous serial communication in which the data format...

amplitude of a series of signal pulses. It is an analog pulse modulation scheme in which the amplitudes of a train of carrier pulses are varied according to the...
