摘要:基于 8751 系列单片机的可变带宽基带信号发生器由控制电路、时钟发生、波形存储、数据输出和放大滤
波等单元组成。通过单片机控制时钟发生、波形存储、数据输出和放大滤波等数字电路,可产生不同频带宽度的基
带正弦扫频信号或不同脉冲宽度的脉冲调制正弦信号。

Abstract: The variable bandwidth signal generator based on the Single Chip puter of 8751 consists of control
circuit, clock generating, waveform store, data output unit and amplification and filter units etc. clock generating,
waveform store, data output unit and amplification and filter circuits etc is controlled single chip puter, and the
baseband sine wave signals of various bandwidth or the pulse modulation sine wave signals of various pulse width is gotten
the puter.
