Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
What does the number of a FM radio station mean?
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 Frequency. The difference between AM and FM radio is that in AM radio the Amplitude is Modulated, or changed to send the signal, whereas with FM, the Frequency is Modulated or altered to send the signal.
How is voice communications converted to digital signals?
The human voice is an analogue signal because the frequency of the sound varies in the sound waves as well as their amplitude that gives the power. Analog signal is defined as a signal that has a continuously varying amplitude or frequency. Human speech, and everything else a human hear, is in analog form.
How do get mobile signal in the presence of mobile signal jammer?
best offers on mobile signal jammer!! you can buy on it spyworld.in
Is saying that a device transmits a signal correct?
Yes, it is correct
Comparison of amplitude modulation and frequency modulation?
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.
When low frequency signals added to high frequency signal then the envelope signal will follow which signal?
the low frequency signal which is nothing but the message signalNeither. The envelope will be that of the difference beat frequency. To get the envelope to follow the low frequency input signal you need to mix (multiply) the two signals, not add them.
What signal has wider bandwidth sine wave with frequency 100HZor 200HZ?
The signal with a frequency of 200Hz has a wider bandwidth compared to a signal with a frequency of 100Hz. Bandwidth is determined by the range of frequencies present in a signal, so a higher-frequency signal will have more frequency components and thus a wider bandwidth.
What does it mean when a radio station is said to have a frequency of 102 megahertz?
When a radio station has a frequency of 102 megahertz (MHz), it means that the station transmits its signal at a wave frequency of 102 million cycles per second. This frequency is part of the VHF (Very High Frequency) band, which is commonly used for FM (Frequency Modulation) radio broadcasting. The specific frequency helps listeners tune in to that station to receive its programming. In practical terms, it allows radios to pick up that station's signal among many others broadcasting on different frequencies.
Why you convert FM signal to IF frequency?
Mix it with a local oscillator whose frequency is (the IF frequency) away from the frequency of the FM signal you're interested in.
Why the linear combination of a low frequency intelligence signal and a high frequency carrier signal is not effective as a radio transmission?
to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver.
What are neurontransmitters?
a chemical that transmits a nervous systems signal across a synapse.
