- during modulation we transmit the signal with a carrier wave with a very high frequency (order of kHz's) high frequency signal will protect the original signal from noise inte…rference as well as signal strength reduction. we use this signal after demodulation at receiver end. 2 people found this useful.

- Notice that the amplitude of the high frequency carrier takes on the shape of the lower frequency modulation signal, forming what is called a modulation envelope. The modulation index is defined as the ratio of the modulation signal amplitude to the carrier amplitude.

AM Radio Band AM and FM Radio Frequencies. The Amplitude Modulated (AM radio) carrier frequencies are in the frequency range 535-1605 kHz. Carrier frequencies of 540 to 1600 kHz are assigned at 10 kHz intervals. The FM radio band is from 88 to 108 MHz between VHF television Channels 6 and 7. The FM stations are assigned center frequencies at 200 kHz separation starting at 88.1 MHz, for a maximum of 100 stations. These FM stations have a 75 kHz maximum deviation from the center frequency, which leaves 25 kHz upper and lower gaurd bands to minimize interaction with the adjacent frequency band.

What was the result of farm mechanization? The principal result of farm mechanization was the removal from the farm of much of human and animal labor and replacing that labor with machines. The resulting improvements in productivity are often misunderstood. It is said 'One farmer in 1950 produced the same output as ten men in 1850.'.

modulation Modulation is the addition of information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform -- constant height (amplitude) and frequency. Information can be added to the carrier by varying its amplitude, frequency, phase, polarization (for optical signals), and even quantum-level phenomena like spin.

What is carrier signal / carrier frequency? Best Answer: A carrier signal is a transmitted electromagnetic pulse or wave at a steady base frequency of alternation on which information can be imposed by increasing signal strength, varying the base frequency, varying the wave phase, or other means. This variation is called modulation.

Carrier frequency 1 Vaguely speaking, the center frequency or the frequency of a carrier wave (radio wave). 2  The nominal frequency or the center frequency of an analog frequency modulation, phase modulation, or double-sideband suppressed-carrier transmission (DSB-SC) (AM-suppressed carrier), radio wave. In very technical language: The nominal frequency or center frequency of various kinds of radio signals with digital modulation -- provided that the message bit stream is a random uncorrelated sequence of equally probable ones and zeroes (marks and spaces).

- Frequency. The frequency of a wave is the number of waves produced by a source each second. It is also the number of waves that pass a certain point each second.The unit of frequency is the hertz (Hz).

Hertz The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves.adio frequency radiation is usually measured in kilohertz (kHz), megahertz (MHz), or gigahertz (GHz). Light is electromagnetic radiation that is even higher in frequency, and has frequencies in the range of tens (infrared) to thousands (ultraviolet) of terahertz.

- The change in frequency, which is greatly exaggerated here, is proportional to the amplitude of the signal. An FM radio carrier around 100 MHz is limited to modulation of +/- 0.1 MHz. Normal FM stereo broadcast is within +/- .053 MHz.
