Pulsed Radio Frequency Wave Forms
The figure below shows an example of a generalized pulsed radio frequency waveform as seen with an oscilloscope with an antenna probe. In this example there are 1000 pulses per second (1 kHz pulse rate) with a gated pulse width of 42 µs. The pulse packet frequency in this example is 27.125 MHz of RF energy. The duty cycle for a pulsed radio frequency is the percent time the RF packet is on, 4.2% for this example ( X 100). The pulse packet form can be a square, triangle, ramp or sine wave. In several applications of pulse radio frequency, such as radar, times between pulses can be modulated.

Famous quotes containing the words radio, frequency, wave and/or forms:
“... the ... radio station played a Chopin polonaise. On all the following days news bulletins were prefaced by Chopin—preludes, etudes, waltzes, mazurkas. The war became for me a victory, known in advance, Chopin over Hitler.”
—Margaret Anderson (1886–1973)
“One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
—Rebecca West (1892–1983)
“When disaster waves, I try not to wave back.”
—Mason Cooley (b. 1927)
““There is no exquisite beauty,” says Bacon, Lord Verulam, speaking truly of all the forms and genera of beauty, “without some strangeness in the proportion.””
—Edgar Allan Poe (1809–1849)
