A Signal is the data being transmitted from one device to another, this includes (but not limited to) binary serial data, pulse width modulation (PWM), sound. The waveform is the shape of the transmitted signal, serial data and PWM would take on a square wave waveform whereas sound from a speaker would appear (generally) as a sinewave.
Not much a of difference between the two, but that is because the two are mutually inclusive to each other.
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.
What is difference between oscillator and regulator ic?
oscillator is which oscillates to a required proportion in order to generate signal with required frequency. whereas, regulator limits the signal to a predefined value and offers a constant out put through out
What is the difference between microwave and an AM signal?
The primary difference is that the microwave signal is of a much higher frequency than an AM signal, if that AM signal is speaking to AM broadcast radio. In general, AM, or amplitude modulation, is not generally used as a modulation technique on microwave frequencies because there are other ways to put a signal on a microwave carrier that allow more information to be transmitted. AM is "low frequency" RF, while FM is a bit higher on the radio frequency spectrum, and microwaves are further on up.
What is the difference between signal processing and signal conditioning?
processing is nothing
Difference between frequency management and channel assignment?
differenve between frequency management and channel assignement
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
What is the difference between a woofer and tweeter?
Woofer is used to reproduce a low frequency signal. But,Tweeter is used to reproduce a high frequency 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
What is the difference between a high frequency UPS and a Low frequency UPS?
The difference is in sine wave generation algorithm. In HI freq - it is 30kHz signal, modulated by 50Hz.
What is the difference between Pitch and volume of a maraca?
Volume (loudness), pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
What is function of an oscillator?
A local oscillator is an electronic device used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer. This process of frequency conversion, also referred to as heterodyning, produces the sum and difference frequencies of the frequency of the local oscillator and frequency of the input signal of interest. These are the beat frequencies. Normally the beat frequency is associated with the lower sideband, the difference between the two.
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 does maximum frequency deviation occur?
Maximum frequency deviation occurs in frequency modulation (FM) when the modulating signal reaches its peak amplitude. This deviation represents the greatest difference between the carrier frequency and the modulated frequency. In practice, it corresponds to the point where the instantaneous frequency of the carrier signal varies the most due to the modulation, often occurring at the maximum input signal level.
What is relationship between signal spectrum and bandwidth?
Signal Bandwidth is the Bandwidth of particular frequency at which signal is transmitted and Bandwidth of spectrum which can able two show number of signal between Intrest of frequency.
Difference between IF and RF signal?
RF signal is coming from an antenna. So it contains electromagnetic waves. But when the signal is processed using electronics circuits, the range of frequency may not be sufficient. So that RF has to be convert to some other frequency acceptable by the circuit. And IF is the intermediate frequency used for tuning & other purpose.
What is signal bandwidth?
Every line has an upper limit and a lower limit on the frequency of signals it can carry. This limited range is called the bandwidth. The signals ranging within the upper limit & lower limit are called bandwidth signals.
What is the difference between baseband and bandpass communication?
Base band signal is transmission of more than single frequency from zero hz to higher frequency components example : base band signal must be modulated to higher frequencies for radio transmission
