What else can I help you with?
When a carrier is phase modulated with an integrated modulating signal the resultant is?
It gives frequency modulated signal
What is the difference between am raido and FM radio?
A: AM radio is an Amplitude Modulation transmission . Meaning it has fix frequency but it is modulated by the signal. FM Frequency Modulation the frequency is modulated by the signal
The amount of frequency deviation for a frequency-modulated signal is determined by the?
The signals frequency directly.
How do you send a digital radio signal to a FM radio?
Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
Why is amplitude of demodulated FM signal much less than modulated signal?
because demodulated FM is an audio signal, which the frequency is much smaller that is why it can be transmitted alone. It need carrier which has large frequency. Modulated signal is an audio signal + carrier that is why the amplitude is higher.
Does the sound transmitter at a television employ frequency or amplitude modulation?
The sound signal of a standard NTSC television signal is frequency modulated.
What is the significance of the delta f over f parameter in frequency modulation?
The delta f over f parameter in frequency modulation is significant because it represents the frequency deviation relative to the carrier frequency. It determines the amount by which the frequency of the modulated signal varies from the original carrier frequency. This parameter is crucial in determining the bandwidth and quality of the modulated signal in frequency modulation systems.
What does fm and am stand for?
AM-Amplitude modulated FM-Frequency modulated Explanation: The frequency and amplitude refer to the width and height of wavelengths in the radio waves that are used to transmit the signal. FM is usually a better signal than AM because the frequency of the waves is less distorted than amplitude.
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
On AM broadcasts what remains constant?
On AM broadcasts, the amplitude of the carrier wave remains constant. This means that the strength or power of the signal does not change, only the frequency of the signal is modulated to carry the audio information.
What is the color subcarrier frequency?
A modulated monochrome signal whose side-bands convey color information.
89kHz sinusoidal signal is modulated using an amplitude modulator and a frequency modulator calculate the bandwdith requirement for both modulation schemes?
You can't do this unless you know more detail on the frequency modulator, like its modulation index, for example or the frequency deviation. For the amplitude modulator, it is easy. Bandwidth is twice the signal frequency so in this case the bandwidth is 178kHz for AM.
