Klystron Tube: What is it? (Types And Applications)

What is a Klystron Tube? A Klystron (also known as a Klystron Tube or Klystron Amplifier ) is a vacuum tube that is used to oscillate and amplify microwave frequency signals. It was invented by American electrical engineers Russell and Sigurd Varian. A klystron uses the kinetic energy of an electron

Quadrature Amplitude Modulation (QAM): What is it?

What is QAM (Quadrature Amplitude Modulation)? QAM (Quadrature Amplitude Modulation) is defined as the modulation technique which is the combination of phase and amplitude modulation of a carrier wave into a single channel. In other words, QAM transmits information by changing both the amplitude and

Relaxation Oscillator: What is it? (And How Does it Work)

What is a Relaxation Oscillator? A relaxation oscillator is defined as a non-linear electronic oscillator circuit that can generate a non-sinusoidal repetitive output signal. A relaxation oscillator was invented by Henri Abraham and Eugene Bloch using a vacuum tube during World War 1. Oscillators ar

Frequency Limitation of an Oscilloscope

Oscilloscopes are an incredibly useful tool of the electronics world after a multimeter . Without a scope, it’s quite difficult to know what is happening in a circuit. But this type of test equipment has its own limitation. To overcome this limitation, one must understand the weakest links in the sy

Measurement of Voltage Current and Frequency by Oscilloscope

Normally, an oscilloscope is an important tool in an electrical field which is used to display the graph of an electrical signal as it varies with respect to time. But some of the scopes have additional features apart from their fundamental use. Many oscilloscopes have the measurement tool that help

Double Beam Oscilloscope

The dual beam oscilloscope emits two electron beams that are displayed simultaneously on a single scope, which could be individually or jointly controlled. The construction and working of the dual beam oscilloscope are completely different from dual trace oscilloscope. The tubes are more complicated

Sampling Oscilloscope

Before discussing sampling oscilloscope , we must know the basic principle and functioning of an ordinary oscilloscope. It is an instrument which receives one or more electrical signals and then produces the waveform on the screen simultaneously. The sampling oscilloscope is an advanced version of t

Digital Storage Oscilloscope

A digital oscilloscope is an instrument which stores a digital copy of the waveform in the digital memory which it analyses further using digital signal processing techniques rather than using analogue techniques. It captures the non-repetitive signals and displays it consciously until the device ge

Strain Gauge: Working Principle & Diagram

What is a Strain Gauge A strain gauge is a resistor used to measure strain on an object. When an external force is applied on an object, due to which there is a deformation occurs in the shape of the object. This deformation in the shape is both compressive or tensile is called strain, and it is mea
