使用DSP产生300—4000HZ的正弦信号，要求使用计算法，并且频率可变、幅度可变、直流分量可变。用软件CCS5500编程实现，并硬件（DSK板或示波器）连接进行功能演示。 使用DSP产生300—4000HZ的方波和三角波。 -Using DSP to produce 300-4000HZ of, sinusoidal signal, require the use of calculation method, and a variable frequency, amplitude v

A barrel shifter is a digital circuit that can shift a data word by a specified number of bits in one clock cycle. It can be implemented as a sequence of multiplexers (mux.), and in such an implementation the output of one mux is connected to the inp
