Internal Noise in Communication System: Under the heading of Internal Noise in Communication System, we discuss noise created by any of the active or passive devices found in receivers. Such…
Sensors and Transducers: The definition of Sensors and Transducers are follows, The input quantity for most instrumentation systems is nonelectrical. In order to use electrical methods and techniques for measurement, the…
Transducers Articles: Electrical Transducer: A transducer is defined as a device that receives energy from one system and transmits it to another, often in a different form. Broadly defined, the…
Peak Reading Voltmeter Circuit: Sometimes it is enough if the Peak Reading Voltmeter Circuit of an impulse voltage wave is measured; its waveshape might already be known or fixed by…
Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a short ultra thin wire…
Pulse Width Modulation(PWM): Pulse width modulation of PTM is also often called Pulse Duration Modulation (PDM). In this system, shown in Fig. 18.8, we have a fixed amplitude and starting…
Null Type Recorder: These Null Type Recorder Working Principle of self-balancing or null conditions. When an input is given to the measuring circuit of the recorder from a sensor or transducer,…
DC Motor Control through Converters: DC motor control is conveniently and efficiently achieved by phase-controlled converters wherein the ac input voltage is converted to a controlled dc output. The commutation…
