Any signal would have four states high indicated by 1, low indicated by 0, high impedance indicated by Z and unknown indicated by X.
An unknown signal often occurs when you have not connected the pin to anything or you are trying to take output from the pin while it is not really giving the proper output

What are analog and digital modes of operation of an instrument?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
What is the difference between signal and event?
The main different between a traditional signal and a message is their recipient. A signal is often sent to a mass of people, while a message is more individualized.
How do you generate double-sideband suppressed carrier?
it can be genrated by multipling of the carrie signal and the message signal that varies the amplitud of the carrire nd supprssd the caarir signal.
What is amplitude modulation and frequency modulation and difference between them?
Both angle and amplitude modulation are involved in radio wavelength patterns. Angle modulation is where the modulating wave manipulates the angle of a sine-wave carrier. The two types of angle modulation include frequency and phase modulation. On the other hand, Amplitude modulation is the strength behind carrying the waveform in radio.
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
What are the longevity for chemical message system?
Speed Longevity purpose What carries the signal Where the signal is transmitted received
What is communicating?
The act of passing information from a sender to a receiver, with a return signal of confirmation of Ten-Four: message received and understood.
What signal is the electrical equivalent of message signal?
Modulating Signal,
How does transponder work?
*"An automatic device that transmits a predetermined message in response to a predefined received signal. * A receiver-transmitter that will generate a reply signal upon proper electronic interrogation. " *Excerpted from Wikipedia ; see related link .

What is the meaning of receiver in communication?
In communication, a receiver is the person or device that receives and interprets the message sent by the sender. The receiver plays a crucial role in the communication process by decoding the message and providing feedback or response to the sender. Effective communication requires clear and accurate message transmission from sender to receiver.

What is a message sent by wire or radio?
A signal. It is a telegram.
How hub handles a signal received in one port?

What does 'no signal' message mean when it appears on the computer screen?
Usually a no signal message means that the video card is not detecting the monitor. An easy way to fix this is to download the latest drivers for your video card and it should detect the monitor.
