Modern Radar Systems Analysis: Modern Radar System are of great importance for both military and civil applications. The main problem of a typical radar system is the detection of return…
Frequency Domain Representation: Frequency Domain Representation - A very important representation of discrete time systems can be obtained in terms of sinusoidal or complex-exponential signals. This is possible because the…
What is Electromechanical Chopper?: Electromechanical Chopper - An ac amplifier must see ac in order to perform useful work. A fair number of chopping and modulation techniques are available to…
Integrator using Op Amp: An Integrator is a circuit that performs the mathematical operation of integration because it produces an output voltage that is proportional to the integral of the…
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 transducer is…
Digital Data Recording System: Digital Data Recording - Digital magnetic tapes are often used as storage devices in digital data processing applications. Digital tape units are of two types, incremental…
Frequency Modulation Recording: When a more accurate response to dc voltages is required, an Frequency Modulation Recording system is generally used. In this FM system, the input signal is used…
Magnetic Tape Recorder Working Principle: The major advantage of using a Magnetic Tape Recorder Working Principle is that once the data is recorded, it can be replayed an almost indefinite…
