What is carrier swing Mcq?

The total variation in frequency from the lowest to the highest point. Frequency deviation above or below the carrier frequency. Width of the side band.

What is carrier swing Mcq?

The total variation in frequency from the lowest to the highest point. Frequency deviation above or below the carrier frequency. Width of the side band.

What is the range of the carrier lifetime Mcq?

What is the range of the carrier lifetime? Explanation: Carrier lifetime is defined as the existence of any carrier for τ seconds. Carrier lifetime ranges from nanoseconds to hundreds of microseconds. 2.

What is amplitude Mcq?

Amplitude modulation : When amplitude of carrier wave is changed according to information signal is called amplitude modulation. e.g. All India Radio Mumbai (1044 KHz). Amplitude modulation is done by the electronic circuit called modulator.

When modulation index is 1 then it is called as Mcq?

Explanation: When the modulation index is 1 or the percentage of modulation is 100, modulating signal voltage is equal to the carrier voltage. This results in the greatest output power at the transmitter and the greatest output voltage at the receiver, with no distortion. 11.

What is carrier swing?

Carrier swing is defined as the total variation in frequency from the lowest to the highest point. The carrier swing = 2* frequency deviation of the FM signal.

What is a carrier swing?

The total deviation of a frequency-modulated or phase-modulated wave from the lowest instantaneous frequency to the highest instantaneous frequency.

A definition in semiconductor physics, carrier lifetime is defined as the average time it takes for a minority carrier to recombine. The process through which this is done is typically known as minority carrier recombination.

What is crosstalk Mcq?

MCQ: Cross talk is – The disturbance caused in the nearby channel or circuit due to transmitted signal. Adjacent frequency rejection.

What is carrier swing of FM wave?

The difference between FM modulated frequency and normal frequency is termed as Frequency Deviation and is denoted by Δf. The deviation of the frequency of the carrier signal from high to low or low to high can be termed as the Carrier Swing. Carrier Swing = 2 × frequency deviation. = 2 × Δf.

What is PM and FM?

Phase Modulation is used in mobile system. 8. In FM, the frequency derivation is proportional to the modulating voltage only. In PM, the frequency derivation is proportional to the modulating voltage as well as modulating frequency.

Where demodulation is done?

Right Answer is: In the case of AMPLITUDE or FREQUENCY MODULATION, it involves a device, called a demodulator or detector, which produces a signal corresponding to the instantaneous changes in amplitude or frequency, respectively. The extraction of the message signal generally takes place in the receiver.

What is carrier swing formula?

Mathematical Representation The difference between FM modulated frequency and normal frequency is termed as Frequency Deviation and is denoted by Δf. The deviation of the frequency of the carrier signal from high to low or low to high can be termed as the Carrier Swing. Carrier Swing = 2 × frequency deviation. = 2 × Δf.

What are majority carriers?

majority carrier in British English noun. the entity responsible for carrying the greater part of the current in a semiconductor. In n-type semiconductors the majority carriers are electrons; in p-type semiconductors they are positively charged holes.

What is a carrier in transportation?

A carrier is a company or a person legally entitled to transport goods by land, water, and air. Usually, the carrier works with shippers to ship goods from one place to the other.

What is life carrier?

A life insurance carrier is an insurance company or issuer of insurance products generally in the main business of providing insurance against disability or death, as well as annuities and pensions.
