Zener Vs Avalanche Breakdown
Zener Vs Avalanche Breakdown Break Down Mechanisms Zener Vs Avalanche Breakdown: When an ordinary P-N junction diode is reverse biased, normally only very small reverse saturation current flows. This current…
Thermocouple
Thermocouple A thermocouple consists of a pair of dissimilar conductors welded or fused together at one end to form the hot or measuring junction with other ends available for connection…
Multiplexing | Frequency Division, Time Division
Multiplexing Multiplexing divides the physical line or a medium into logical segments called channels. In multiplexing, different channels carry data simultaneously over the same physical medium. Hardware equipment called multiplexer…
Routh-Hurwitz Stability criterion
Routh-Hurwitz Stability criterion The Routh-Hurwitz Stability criterion gives the information on the absolute stability of a system without any necessity to solve for the closed-loop system poles. This method helps…
Concept of Stability | Control System
Concept of Stability Concept of Stability: A system is said to be stable if it does not exhibit large changes in its output for a small change in its input,…
Folded Dipole Antenna
Folded Dipole Antenna A folded dipole antenna is a modified λ/2 dipole with an additional wire connecting its two ends. The folded dipole antenna is an extremely practical wire antenna…
Insulated Gate Bipolar Transistor (IGBT)
Insulated Gate Bipolar Transistor (IGBT) There are numerous types of power semiconductor switches and among these switches, the insulated gate bipolar transistor (1GBT), which combines some of the features of…
Electromagnetic (EM) Wave Propagation
Electromagnetic (EM) Wave Propagation Electromagnetic (EM) Wave Propagation: Electromagnetic wave in the frequency spectrum of 0.001 to 1016 Hertz is arbitrarily termed as radio waves, although broadly speaking by radio…
Diversity Techniques in Wireless Communication
Diversity Techniques Diversity is a good technique applied in mobile communication receiver circuits where there are multipath environments. The diversity techniques use the nature of the propagation path characteristics for…
Ground (Surface) Wave
Ground or Surface Wave A wave is said to be a ground wave or surface wave when it propagates from transmitter to receiver by gliding over the surface of the earth. This wave exists…
