（Root Raised Cosine Filter）根升余弦滤波器的MATLAB代码
测试测量 基于Multisim 10的矩形波信号发生器仿真与实现
在Multisim 10软件环境下，设计一种由运算放大器构成的精确可控矩形波信号发生器，结合系统电路原理图重点阐述了各参数指标的实现与测试方法。通过改变RC电路的电容充、放电路径和时间常数实现了占空比和频率的调节，通过多路开关投入不同数值的电容实现了频段的调节，通过电压取样和同相放大电路实现了输出电压幅值的调节 ...

tServer task executes functions at low priority (254). serverSend
funtion is used to send a request to the tServer to execute a
function at the tServer s priority.
First tServer task executes the i() system call to print the summary
of tShell task. Next an address exception is caused i ...

Modify the Gray-coded modulation example (COMMDOC_GRAY)
so that it uses a pair of square root raised cosine filters
to perform pulse shaping and matched filtering at the
transmitter and receiver, respectively.
