A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz… Full Answer
RF Shielding actually has little to do with the magnetic field generated by an MRI Scanner. The purpose of The RF Shielding installed in an MRI exam room is to prevent radio frequency interference from entering into the MRI Scanner… Full Answer
The difference is their position on the electromagnetic spectrum. radio waves are on the low frequency / long wavelength end of the spectrum. X - rays and Gamma rays are on the high frequency / short wavelength end. The only… Full Answer
The frequency of a radio wave compares to the frequency of the vibrating electrons that make it because the frequency of a radio wave is proportional to the frequency of the vibrating electrons that make it.
Single phase and three phase voltages are not related to the frequency at which the voltage is generated. The frequency at which voltages are generated is governed by the speed of rotation of the generating device.
Compared to what ? Radio waves have very high frequency compared to ocean waves, El Niño, and the business cycle. Radio waves have high frequency compared to sound and ultrasound waves. Radio waves have low frequency compared to infrared waves… Full Answer
No. If a wave has the frequency of radio, then it's a radio wave. If it has the frequency of light, then it's a light wave. You can't see the radio waves that fill all the space around you, or… Full Answer
Radio use radio waves (one with largest wavelength). Radio station broadcast its program via FM or AM frequency and antennas pick up the signal and when we turn our radio knob to particular frequency we are resonating to the broadcast… Full Answer
The definition of what it is, is actually in your question. It's a receiver that operates in the radio frequency spectrum. Anything that has a transmitter is said to transmit in radio frequency or `RF`. The term radio is short… Full Answer
Radio communication works on radio signals that are "beamed" into the air on a certain frequency. Frequency is a certain wavelength or band. The receiving equipment has to be set to receive the signal on the same frequency.
This is a highly technical subject. It is not possible, or desirable, to fully explain it here. Basically electromagnetic waves of the appropriate frequency are generated, these are then manipulated (called modulation) in various ways to carry information.
The numbers in an FM radio station represent the frequency the station transmits the signal on. The frequency range for FM band radio stations is from 87.5 MHz to 108.0 MHz. These radio frequencies are considered VHF or Very High… Full Answer
They terms frequency are essentially the same, except radio waves are electromagnetic, and acoustic waves are pressure waves. An audio frequency is a range of frequencies that we can hear, approx up to 20Khz, anything past 20Khz is said to… Full Answer
