In electronics circuits, the signal is associated with an AC (Alternating current) and DC (Direct Current). The sinusoidal wave or sine wave represents the periodic AC signal that varies with time and fluctuates between positive and negative cycles. While DC signal/waveform represents the magnitude of voltage and current values easily and stable. But the magnitude of the current and voltage values of the AC signal should be calculated by using its instantaneous values, a peak value of the … [Read more...]
What is Wave Analyzer : Working & Its Applications
In electronics and communications, the periodic signal is represented in the form of DC component and some sinusoidal harmonics. It is necessary to analyze the harmonics present in the signal. So, wave analyzers are used to measure the amplitude of the harmonics in the domain of frequency with the help of tuned filters and voltmeters. The wave analyzer can be tuned to analyze the frequency of the harmonic component of the signal whose amplitude is to be measured. Here is a complete description … [Read more...]
What is an Attenuator : Design, Types & Its Applications
Electricity, communication, entertainment, utility resources (gas), etc. everything is required to be transmitted from one point to another. For transmitting these, there are different type of technologies and transmitting techniques. Electrical power generated at one place is transmitted to consumer point using transmission lines along with required substations. For transmitting power from one point to another point, amplifiers are used to increase the power of signal and are called as … [Read more...]
