Difference Between Frequency Modulation and Amplitude Modulation: The Difference Between Frequency Modulation and Amplitude Modulation are discussed below The frequency modulation (FM) has the following advantages over the amplitude modulation (AM) : 1. FM receivers may be fitted with amplitude limiters to remove the amplitude variations caused by noise. This makes FM reception a good […]

Difference between Voltage Amplifier and Power Amplifier: The Difference between Voltage Amplifier and Power Amplifier are discussed below The primary function of the voltage amplifier is to raise the voltage level of the signal. It is designed to achieve the largest possible gain. Only very little power can be drawn from its output. The voltage

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

Difference between LED and LCD: The Difference between LED and LCD is given in table below Light Emitting Diode – LED Liquid Crystal Display – LCD Needs more power (10-250 mW per digit). Essentially acts as a capacitor and needs very less power (10-20 μW per digit). Because of high power need, it needs external

Difference between Linear Power Supply and SMPS: The Difference between Linear Power Supply and SMPS is given in table below Features Linear Power Supply SMPS Efficiency 25-50 per cent 65-75 per cent Temperature rise 50-100 °C 20-40 °C Ripple value Even 5 mV possible Higher, 25 to 50 mV Overall regulation Even 0.1% is possible

Difference between Analog Storage and Digital Storage Oscilloscope: The Difference between Analog Storage and Digital Storage Oscilloscope is given in table below Analog Storage Oscilloscope (ASO) Digital Storage Oscilloscope (DSO) In this Oscilloscope heavy amount of power is to be supplied to the storage CRT. It can store the given indefinitely as long as the small

Difference between Zener Breakdown and Avalanche Breakdown: The difference between Zener Breakdown and Avalanche Breakdown is given in table below Zener Breakdown Avalanche Breakdown This is observed in zener diodes having reverse voltage of less than 5 volts. This is observed in zener diodes having reverse voltage of 5 or more volts. The valance electrons
