Analog Carrier System is a transmission system that uses repeaters that compensate for analog medium impairments, and produce output signals that are linear-scaled versions of input signals. Analog carrier systems can carry speech, data, video and supervisory signals although they are best suited for speech signals.

What is carrier telephony and what are the features of carrier telephone system?
Carriers are the companies that construct and maintain the networks that provide telephone services. Carrier telephony is a method of transmitting several telephone channels over a single pair of wires. It was used extensively throughout the world in the 1940s through 1980s prior to the introduction of digital transmission systems. Carrier telephony systems ranged from single channel systems that transmitted one carrier channel on top of a normal voice frequency channel to co-axial cable systems that had thousands of channels. It was mostly used to provide trunk lines between cities although subscriber carrier systems did exist.
What are the differences between analog and digital filters?
The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What is one disadvantage of an amplitude modulation communication system?
One disadvantage of the standard amplitude modulation system is that 67% of the power is used for the carrier, but the carrier transmits no information, so it can be considered as wasted power.The 34% remaining power is split between two mirror opposite sidebands so, in effect, you really only have 17% of your power used to carry the signal.
What is convert analog to digital convert?
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.

What modulation is used in telegraphy system?
pulse code modulation method used a telephony.
What is analog simulation?
Analog system simulation is more sensitive to the changes in the parameters compared to the digital system. This is because of the continuous nature of the analog signals, unlike the discreet nature of the digital signals. Digital systems have gates which can not be used in Analog system.

What is analog modulation?
Analog modulationIn analog modulation, the modulation is applied continuously in response to the analog information signal.Common analog modulation techniques are:Amplitude modulation (AM) (here the amplitude of the modulated signal is varied) Double-sideband modulation (DSB) Double-sideband modulation with unsuppressed carrier (DSB-WC) (used on the AM radio broadcasting band)Double-sideband suppressed-carrier transmission (DSB-SC)Double-sideband reduced carrier transmission (DSB-RC)Single-sideband modulation (SSB, or SSB-AM), SSB with carrier (SSB-WC)SSB suppressed carrier modulation (SSB-SC)Vestigial sideband modulation (VSB, or VSB-AM)Quadrature amplitude modulation (QAM)Angle modulation Frequency modulation (FM) (here the frequency of the modulated signal is varied)Phase modulation (PM) (here the phase shift of the modulated signal is varied)
How secure is a computer telephony software?
Computer Telephony Software is very secure. Computer Telephony Software is commonly used to automate or manage telephone calls, such as in Call Centers.

What is analog TV?
Analog television was first used in the 1930s. Analog signals are sent by varying voltage, radio frequencies, and static images.
