设计一个简易数字信号ASK调制系统。系统数字基带信号V1为m序列伪随机信号，载波信号V2为正弦波周期信号，V3为V1经二进制幅移键控调制后的输出。系统输入为CLOCK和RESET信号，CLOCK是系统时钟信号，上升沿触发。RESET为系统异步复位信号，高有效。(A simple digital signal ASK modulation system is designed. The system digital baseband signal V1 is m sequence pseudo random signal, carrier signal V2 is sine wave periodic signal, V3 is V1 after binary amplitude shift keying modulation output. The system inputs are CLOCK and RESET signals, CLOCK is the system clock signal and the rising edge triggers. RESET is a system asynchronous reset signal, which is highly effective.)
