The intelligence signal is in the AM envelope.
In AM modulation, the carrier is amplitude modulated by the signal. This signal appears as the envelope of the carrier. You can demodulate it by following the peaks on each cycle of the carrier. You can either follow the positive peaks or the negative peaks - it does not matter if the original modulation is symmetrical.
What else can I help you with?
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.
When you do modulation in time domain you get modulated waveform of modulating signal information and carrier. How can you recognize the upper and lower side bands in time domain modulated waveform?
You need modulation signal(carrier) which is a required signal in order to make envelope of time domained signal(target signal). The modulating signal is imposed on modulation signal.This creates envelope of waveform which is modulated(desired) signal. Now, the desired signals uper and lower sideband of signal strictly depends on modulation signal's bandwidth. Max. peak of that signal is uper sideband and min. peak is lower sideband for this modulated signal.
What type of modulation produces pulses whose duration is proportional to the amplitude of the intelligence signal?
Pulse-Amplitude Modulation
How the envelope detector converts a 455 khz am signal to the message signal?
The diode flips the entire signal to the positive region like a rectifier. Then the parallel rc combination is kept charged or discharged by the carrier frequency, 455kHz. Since the Signal sits on top of the carrier, the output is the original sent signal with some ripple distortion, this can be taken care of with a simple lowpass rc filter
What are agricultural robots work envelope?
the work envelope is 78 degrees
What is meant by Repetition rate of an AM envelope?
Repetition rate of an AM envelope refers to the frequency of the modulating signal thus the shape of the envelope is identical to the shape of the modulating signal.
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.
1 What is meant by envelope of an AM waveform?
The envelope of an AM waveform is a curve outlining the peaks of the modulated signal. It represents the variations in amplitude caused by the modulation process. The envelope is essential for demodulating the signal to recover the original message.
What is the significance of the Gaussian envelope in signal processing and how does it affect the characteristics of the signal?
The Gaussian envelope is important in signal processing because it helps to shape and modulate the signal. It affects the characteristics of the signal by controlling its amplitude and frequency distribution, making it useful for filtering and smoothing signals.
What are the sub-intelligence disciplines in signal intelligence?

What is the envelope of a signal?
The envelope of a signal is the "apparent" signal seen by tracking successive peak values and pretending that they are connected. Normally, this question involves amplitude modulation of a radio frequency carrier by an audio frequency signal. The two frequencies involved are very much different - 20 kHz versus 1 mHz, for instance, and this "envelope" effect will be very noticable on an oscilloscope.
