Pulse Modulation Tutorial Electronics Pulse Modulator General Theory, Tutorials and Circuits Pulse modulation consists of switching the carrier on and off as required. Fig.1 shows a continuous wave carrier (CW). Fig.2 shows the carrier being switched on for a short time to produce a pulse of R.F. This is the principle of Radar; a short pulse is transmitted and then an echo listened for.Modulation
In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal that typically contains information to be transmitted.Most radio systems in the 20th century used frequency modulation (FM) or amplitude modulation (AM) for radio broadcast.. A modulator is a device that performs modulation.Pulse forming network
A pulse forming network (PFN) is an electric circuit that accumulates electrical energy over a comparatively long time, and then releases the stored energy in the form of a relatively square pulse of comparatively brief duration for various pulsed power applications. In a PFN, energy storage components such as capacitors, inductors or transmission lines are charged by means of a high voltage ...Technical Note: Electro Optic Modulator FAQs Newport
A: Amplitude modulators basically consist of an electro optic modulator followed by a polarizer. If the input polarization is oriented at 45° to the crystal axes, the applied voltage will produce a variable phase delay between the ordinary and extraordinary field components, simulating a voltage tunable waveplate.Radar Basics
A pulse radar is a radar device that emits short and powerful pulses and in the silent period receives the echo signals. In contrast to the continuous wave radar the transmitter is turned off before the measurement is finished. This method is characterized by a radar pulse modulation with very short transmission pulses (typically transmit pulse durations of τ ≈ 0,1 … 1 µs). .fairchildsemi LM555 NE555 SA555
