some LAB Pen test

1 . Write the Nyquist frequency of the following signals
（1）f（t）＝1＋cos（2000pait）＋sin（4000pait）
（2）f(t)=sin(4000pait)/pait
(3)f(t)=(sin(4000pait) The square of )/pait
2. Fill in the procedure
Put a calculation m^n The general meaning of complete program filling is ： There is a global array char s[BUFSIZE] Use this array to calculate , Namely
Each cell stores one bit of the calculation result ,index Small storage low position ,index Large storage high position
3. There are two threads
void producer()

ProcessPackets();
}
}
}
（1） Is there any other way to improve the performance of the program
（2） Can the above functions be realized without using mechanisms such as signals
