BWO is an abbreviation used for Backward Wave Oscillator. It is a special type of vacuum tube used to produce microwave signals in the range of Terahertz (THz). Backward wave oscillator belongs to the group of Travelling Wave Tubes that generates oscillations at microwave frequencies. Backward wave oscillators are also known as Carcinotrons. As both …
IMPATT is an abbreviation used for IMPact ionization Avalanche Transit-Time. IMPATT diode is a very high power semiconductor device that is utilized for microwave applications. It is basically used as oscillator and amplifier at microwave frequencies. The operating range of the IMPATT diode lies in the range of 3 to 100 GHz. Basically it possesses …
Definition: Directional Coupler is a passive network that is used to measure the microwave power delivered to the load. It is a waveguide with 4-ports which aims at sampling of microwave power. In a nutshell, directional couplers allow the determination of delivered power to the load from the power actually being transmitted by the source. …

It is an 18 pin chip. 8284 produces the clock signal, synchronizes it with the ready and reset signal and provides it to the microprocessor. Functions of 8284 It provides a stable clock to …
Definition: Assembler directives are the instructions used by the assembler at the time of assembling a source program. More specifically, we can say, assembler directives are the commands or instructions that control the operation of the assembler. Assembler directives are the instructions provided to the assembler, not the processor as the processor has nothing to …
Assembly language programming is a low-level programming language in which the instructions are written in the form of mnemonics. More simply, we can say the language in the form of mnemonics is known as assembly language. This programming language allows the creation of human-readable program equivalent to machine code. Now a question arises: What are …
Definition: Radar Clutter is defined as the unwanted back-scattered signals or echoes generated from physical objects in the natural environment like ground, sea, birds, etc. Due to the presence of clutter the detection of target by the radar system in the environment becomes difficult. Sometimes there exist multiple scatterers in the environment that produces unwanted …
Definition: A monochrome picture tube is a specialized CRT that produces a black and white image on the screen of the tube by the action of an electron beam. The screen of the tube consists of a layer of phosphor that produces light when a high-velocity beam strikes it. A picture tube basically acts as …
