Theory of Frequency Modulation and Phase Modulation: Frequency Modulation and Phase Modulation is a system in which the amplitude of the modulated carrier is kept constant, while its frequency and rate of change are varied…
The Sine Wave: Many a time, alternating voltages and currents are represented by a sinusoidal wave, or simply a sinusoid. It is a very common type of alternating, current (ac) and alternating voltage. The sinusoidal…
Testing of Semiconductor Diode: There are Several methods are available for Testing of Semiconductor Diode, namely, Ohmmeter Tests: One of the simplest and quickest tests can be made using an ohmmeter to measure the forward and…
Testing of Overcurrent Relay: Test benches are used for proving the design characteristics of relays. These are provided with accurate timing apparatus and calibrated current and voltage supplies. The basic circuit for Testing of Overcurrent…
Testing of DC Machine or Swinburne Test: Testing of DC Machine or Swinburne Test - Machine efficiency, in general, has been discussed already. The approach here will be to apply the general principles for the…
Terminal Pairs or Ports: Terminal Pairs or Ports - A pair of terminals at which an electrical signal may enter or leave a network is called a port. The terminals or port is required for…
Terminal Characteristics of Junction Diodes: The volt-ampere characteristic of a silicon junction diode is depicted in Fig. 7.14. The same Terminal Characteristics of Junction Diodes is depicted in Fig. 7.15 with some scales expanded and…
Temperature Effect on Semiconductor Diode: Diode Power Dissipation - The power dissipation in a diode is simply calculated as the device terminal voltage multiplied by the current level. Device manufacturers specify a maximum power dissipation…
Temperature Controls using an Analog Electronic Controller: A Temperature Controls scheme using an Analog Electronic Controller of Fig. 21.14 is as shown in Fig. 21.16. The temperature setting, derived from a slide wire, is compared with the…
Temperature Control System: Before going to study the temperature control system, let us see the block diagram of microprocessor based process Temperature Control System. It is capable of controlling more than one physical parameter. Such…
