2 Modem Modulator - Demodulator Modulator - Demodulator -Converts digital information into audible tones -Uses Switched Telephone Network Telephone optimized for human voice - centered on 3kHz bandwidth Telephone optimized for human voice A modulator-demodulator, or modem, does both. (Thanks to Bill Paul's reply.) Modulator is a device that modulates the the message signal (i.e the signal which you want to transmit to another place) with a carrier signal of very high frequency. for demodulator , it is the device that separates the A modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier MODEM abbreviation stands for Modulator/Demodulator. Modulator/Demodulator can be abbreviated as MODEM. What is MODEM abbreviation? FM Modulator-Demodulator Rst Qx Qy Qz 16 We implement our pipelined CORDIC into an All- 16 16 Digital FM Modulator-Demodulator. Frequency Modula- tion (FM) is used in many applications such as audio and Cos Sin video broadcasting systems, telemetry, radar, etc. The CORDIC is applied in Functions • Alignment-free FM modulator and demodulator of 4.5MHz. • A listing of SCILLC's product/patent coverage may be accessed at onsemi.com/site/pdf/Patent-Marking.pdf. SCILLC reserves the right to make changes without further notice to any products herein. 3 Implementation of Demodulator The demodulator operates in closed-loop mode with the PC and an external LPF, as shown in Figure 5. PC output followed by LPF represents the demodulated signal, which is the equivalent of the original digital information. modulator demodulator Datasheet PDF File. th FEC and Upstream QPSK/16-QAM modulator DAVIC MAC Ver 1.2/1.5 Silicon Tuner Analog NTSC BCM7014 Graphics Engine with NTSC Encodemodulator with universal FEC supporting a picture IF input and a 10-bit ADC, a QPSK Comtech EF Data CDM-710 Manual Online: Modem (modulator+demodulator) Commands And Queries.

Modulator-Demodulator stands for modem. Asked in Computer Hardware. Mo-dem Modulator / Demodulator Converts at one end then reverses at the other end Modem = modulator-demodulator, and is a tool for tweaking an analog signal so that it can be used in a digital device. A modem (from modulator-demodulator) can perform both operations. The aim of analog modulation is to transfer an analog baseband (or lowpass) signal, for example an audio signal or TV signal, over an analog bandpass channel at a different frequency, for example over a limited radio The proposed FM modulator and demodulator has been implemented and tested using XC2VP30-7ff896 FPGA as a target device and can operate at The FM modulator consumes 107.67 mW power while FM demodulator consumes 108.67 mW power for the same input running at sam
