Signal Conditioning of Inputs: Since all the data that have to be acquired, do not generally originate from identical sources, signal conditioning becomes necessary in some cases. A simple attenuator,…
Radio Frequency Modulation: Radio Frequency Modulation - The simplest method of measuring frequency deviation utilises an FM receiver with a BFO as the measuring instrument. The only coupling used is…
Modulation Frequency Definition: Modulation Frequency Definition is the process of impressing information on a carrier wave by altering either its amplitude of frequency. In amplitude modulation, the degree is the…
Audio Amplifier Frequency Response: The Audio Amplifier Frequency Response is essential for filters, couplings circuits, amplifier stages and overall audio circuits. An amplifier stage is used as an example. A…
Types of Unit System: All physical quantities are measured in certain units. There are two Types of Unit System, namely: Fundamental units Derived units Fundamental Units: All the physical quantities…
CCIF Intermodulation Distortion: In the second method of carrying out an CCIF Intermodulation Distortion test, the two test signals used have equal amplitude, and relatively high but slightly different frequencies.…
Nonlinear Distortion Measurements: One of the methods of Nonlinear Distortion Measurements consists of simultaÂneously applying two sinusoidal voltages of different frequencies to the amplifier input and observing the sum, difference…
Microwave Power Measurement Techniques: Microwave Power Measurement Techniques can be done by the use of wavemeters. A wavemeter is an adjustable resonant circuit provided with a calibration that gives the…
