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

£oIn this paper, based on analysis of existing signal generator according to the system of indicators to a reasonable use of single-chip high-frequency precision function generator MAX038 control to produce the periodic waveform of the triangle wave, sine wave and square wave three. MAX038 chip as the core, the use of converters, digitally controlled potentiometers, electronic switches, proportional amplifier waveform type, amplitude, frequency programmable to adjust. The design frequency of mediation a wide range of high stability, and display are intuitive and easy to control. The high precision affordable price can be widely used in a variety of electronic measurement and control applications. Confirmed by the measurement of the effectiveness and feasibility of this program.

this paper introduces an output method of arbitrary waveform signal on the FPGA by uses DDS principle. Arbitrary waveform dates produced by the upper machine are downloaded to the waveform RAM of the DDS through the serial port, and realize the control of frequency and phase by using single-chip microcomputer. The upper machine with using LabWindows/CVI software design, realizes arbitrary waveform output.
