Multiple signals can be transmitted over the same transmission channel using techniques such as Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), and Code Division Multiple Access (CDMA). TDM allocates different time slots to each signal, while FDM assigns different frequency bands to each signal. CDMA uses unique codes for each signal, allowing them to occupy the same frequency band simultaneously without interference. These methods enhance the efficiency of channel utilization and increase the capacity of communication systems.

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.

When several signals can be transmitted at once it is called?
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
What is signal rate?
Signal rate refers to the frequency at which data is transmitted over a communication channel, typically measured in bits per second (bps). It indicates how many bits of information can be sent in a given time period, influencing the speed and efficiency of data transfer. In digital communications, a higher signal rate generally allows for faster transmission of information but may require more bandwidth and can be affected by noise and interference.
Analog transmission using fiber optic system?
The transmission characteristic of a fiber optic channel is highly non-linear. It makes it a very bad medium for analog signals. Luckily it doesn't interfere with digital transmissions.
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
Is FDM is an example of parallel transmission?
Frequency Division Multiplexing (FDM) is not an example of parallel transmission; rather, it is a method of multiplexing that allows multiple signals to be transmitted simultaneously over a single communication channel by assigning each signal a different frequency. In FDM, each signal occupies a unique frequency band within the overall bandwidth, enabling concurrent transmission without interference. Parallel transmission, on the other hand, involves sending multiple bits simultaneously over multiple channels or wires.
Analog & digital communication?

What are the basics of communication system?
The basic elements that form a communication system are : -The transmitter : which processes the input signal to produce a transmitted signal suited to the characteristics of the transmission channel. Signal processing for transmission almost always includes modulation and may include coding. -The transmission channel : which is the electrical medium that bridges the distance from source to destination.It may be a pair of wires, coaxial cable, or a radio wave or laser beam.Every channel experiences some amount of transmission loss or attenuation, so the signal power progressively decreases with increasing distance. -The receiver : operates on the output signal from the channel in preparation for delivery to the transducer at the destination. Receiver operations include amplification to compensate for transmission loss, and demodulation and decoding to reverse the signal-processing performed at the transmitter. Filter is another important function of the receiver.
What are the range of frequencies that can be transmitted called?
The range of frequencies that can be transmitted is called the bandwidth. It refers to the range of frequencies within a signal that can be effectively transmitted through a communication channel.

What is the role of multiplexers in signal transmission?
A multiplexor is used to encode multiple input signals for transmission over a single channel. This works because the bandwidth of the output channel is higher than the bandwidth of the input signals, allowing the input signals to share the output channel. At the other end, a de-multiplexor decodes the channel and decodes the individual input signals.
What key features affect the channel capacity?
Key features that affect channel capacity include bandwidth, signal-to-noise ratio, and modulation technique. A wider bandwidth allows for more data to be transmitted, while a high signal-to-noise ratio enables better accuracy in data transmission. The modulation technique used can also impact channel capacity by determining how efficiently the available bandwidth is utilized.
What is noiseless channels?
A noiseless channel is a communication channel where no errors or interference occur during signal transmission. This means that the transmitted message reaches the receiver exactly as it was sent by the sender, without any degradation in quality or information loss. Noiseless channels are ideal for reliable and accurate communication.
