Key Terms - Chapter 8 analog signal. Signals that represent a range of frequencies, such as the human voice. They are a continuous electronic wave signal as opposed to a digital signal that is either on or off. To convert the digital signals of your computer to analog and vice versa, you need a modem. Another cable connects the modem to the telephone wall jack.

A Beginner's Guide to Digital Signal Processing (DSP) To illustrate this concept, the diagram below shows how a DSP is used in an MP3 audio player. During the recording phase, analog audio is input through a receiver or other source. This analog signal is then converted to a digital signal by an analog-to-digital converter and passed to the DSP.ignals need to be processed so that the information that they contain can be displayed, analyzed, or converted to another type of signal that may be of use. In the real-world, analog products detect signals such as sound, light, temperature or pressure and manipulate them.

Comparator In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger.It has two analog input terminals and and one binary digital output. The output is ideally. A comparator consists of a specialized high-gain differential amplifier.They are commonly used in devices that measure and digitize analog signals, such as analog-to-digital converters (ADCs), as well as relaxation oscillators.pecific rail-to-rail comparators with p-n-p input transistors, like the LM139 family, allow input potential to drop 0.3 volts below the negative supply rail, but do not allow it to rise above the positive rail.

Communication Networks/DSL A splitter is combined with the NID. It is an analog filter that separates the 0-4000 Hz band used by the POTS from the data. The POTS signal is routed to the telephone, and the data signal is routed to the ADSL modem. The ADSL modem is connected to the computer through an Ethernet card or USB port.

What are Digital and Analog Signals? - Definition & Explanation As we speak into a microphone, sound waves from our voice are transmitted by the telephone in the form of radio waves (both sound waves and radio waves are analog signals), and when combined with digital signals, we begin moving data along the telephone line.

RS-232 In telecommunications, RS-232, Recommended Standard 232 is a standard introduced in 1960 for serial communication transmission of data. It formally defines the signals connecting between a DTE (data terminal equipment) such as a computer terminal, and a DCE (data circuit-terminating equipment or data communication equipment), such as a modem. The RS-232 standard had been commonly used in computer serial ports.

Cable telephony From Wikipedia, the free encyclopedia. Cable telephony is a form of digital telephony over cable TV networks. A telephone interface installed at the customer's premises converts analog signals from the customer's in-home wiring to a digital signal, which is then sent over the cable connection to the company's switching center. The signal is then sent on to the public switched telephone network (PSTN). Cable telephone provides another revenue stream for cable television system operators and gives the consumer the convenience of a single bill for combined television, internet and telephone services.

A Beginner's Guide to Digital Signal Processing (DSP) In the real-world, analog products detect signals such as sound, light, temperature or pressure and manipulate them. Converters such as an Analog-to-Digital converter then take the real-world signal and turn it into the digital format of 1's and 0's. From here, the DSP takes over by capturing the digitized information and processing it. It then feeds the digitized information back for use in the real world.

- The word modem is short for modulator-demodulator which is essentially what it does. A computer moves data around on parallel wires by applying one or another voltage to e … ach wire (representing 0's and 1's) and the voltage is read at the other end of the wires.t comes from the term MOdulator DEModulator. A modem converts a digital signal from a computer into an analog signal, so that can be transferred down a telephone line and then at the other end it is converted back into a digital signal so that it can be sent into the receiving computer.

What is an analog telephone line? Similarly, every phone extension in your office has access to the public switched telephone network through a smaller set of analog telephone lines. If you have a small office (1 3 phones), each telephone can be connected to the local loop and then receive its' own phone line.However, if your office is growing and you need to connect many phone extensions to the PSTN, it just doesn't make financial sense to pay for separate lines to each phone.hen you speak into the handset of your phone, the microphone converts the sound waves into analog electrical waves. These waves propagate over the telephone line to their destination. The receiving phone then converts the the electrical signals back into sound waves through the speaker of the handset.
