Abstract
This system consist of five modules , which are clip processor , D/A-controlled voltage convertible module , Key-displayed processing module , wave-generated unit circuit module, Inputting signal frequency provided to output function required into ⑶single-clip processor through the key. The signals were transferred to digital-code tube display. The control voltage turned out by single-clip processor produced by wave-generated unit module to change the amplification of control voltage, which realizes the adjustment of frequency. This system has several characters as follows:
⑴ Outputting sin-wave, square-wave and tringle-wave etc;
⑵ Output frequency varies from 20Hz to 10KHz, out frequency can be adjusted continuously and its resolution is 0.1Hz;
⑶ The amplification of output wave can be adjusted continuously;
⑷ The output power≥2W
⑸ Automatic scan(step is 0.1Hz,step is per step);
⑹ It can output solid frequency of random, from 20Hz to 10KHz;
⑺ Digital display, minimum unit is 0.1Hz.
