ECG Signal Generator Design Based On DFG Model

Signal generator is electronic equipment which can produce standard signals, and it often is used in industrial production electronic laboratories and the electronic equipment. Signal generator can achieve in a variety of methods, and the higher frequency and the more waveform is the better the signal generator condition. We can consider its implementation from the production and using areas. This paper will use function in the external circuit chip ICL8038 and electronic way to produce triangle wave, sine wave, rectangular wave,which are three basic rectangular waveforms, then the wave through ICM7216D, crystal, capacitors, switches and LED digital which are composed of the circuit to show the frequency and makes the sine wave produce a frequency modulation wave through FM circuit.

Rf Signal

Radio frequency signal generators (RF) are instruments used to test reception equipment and RF components like filters, amplifiers, attenuators, among others. On the other hand, they reinforce the teaching-learning processes and they are widely used in research in the telecommunications field. This document provides the first stage of a low-cost signal generator design by using RaspBerry Pi 3, with the documentary exploration about this kind of applications. After that, a recognition of the RaspBerry Pi 3 is done at hardware and software level. Finally, an application of an FM signal generator with RaspBerry in a frequency of 101.3 MHz is evaluated, which does not require any additional hardware. This signal was captured using a spectrum analyzer, which determined good quality of the modulated signal in terms of power, bandwidth and SNR (Signal Noise Ratio). However, there are some unwanted harmonic components
