Difference Between Thyristor and Transistor: As already mentioned, transistors and thyristors are both semiconductor devices. They are now widely employed in switching operations because of their numerous advantages such as noiseless operation owing to absence of moving parts, very high switching speed (say 109 operations per second), high efficiency, low maintenance, small size, little weight …
Difference Between Thyristor and Thyratrons: Before the discovery of thyristors, thyratrons were used for industrial control, but now they have been replaced by the thyristors because of the following drawbacks of thyratrons. 1. Thyratron needs a large anode to cathode supply voltage and a separate filament supply whereas the thyristor needs only one main supply …
Difference Between Frequency Modulation and Phase Modulation: The Difference Between Frequency Modulation and Phase Modulation are discussed below FM and PM are quite similar except by the manner in which the modulation index is defined. 1. For FM, the phase angle is proportional to modulating wave whereas for PM, the time derivative of phase angle …

Difference between NMOS and PMOS: The Difference between NMOS and PMOS is given below 1. P-channel is much easier and cheaper to produce than the N-channel device. 2. The drain resistance of P-channel MOSFET is three times higher than that of an identical N-channel device. 3. The N-channel MOSFET is smaller for the same complexity …
Difference between JFET and MOSFET: The Difference between JFET and MOSFET are quite similar in their operating principles and in their electrical characteristics. However, they differ in some aspects, as detailed here : 1. In MOSFETs (DE-MOSFETs as well as E-MOSFETs), the transverse electric field induced across an insulating layer deposited on the semiconductor material …
Difference Between PAM, PWM and PPM: The Difference between PAM, PWM and PPM is given below: PAM PWM or PDM PPM Amplitude of the pulse is proportional to the amplitude of modulating signal. Width of the pulse is proportional to amplitude of modulating signal. The relative position of the pulse is proportional to the amplitude …
Difference between LED and Laser Diode: The Difference between LED and Laser Diode is given below: As already mentioned LASER is the shortened form of light amplification by stimulated emission of radiation. A laser emits radiation of essentially one wavelength, or a very narrowband of wavelengths. This means that the light has a single colour …
