数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符...

模拟银行卡取款操作，银行卡号为8位，能够进行查询、取款、存款、修改密码等操作。查询时需要输入密码，密码为6位。当密码位数和相应位都符合时，显示卡内余额，否则密码三次错误，结束操作。取款时也需要输入密码，密码为6位。当密码位数和相应位都符合时，显示现有余额，输入取款金额，操作结束显示所剩金额，否则密码三次错误，结束操作。限制每天总共可取的金额 ，若违规给出相应的警告。取款操作时输入取款金额 ，操作结束，显示卡内余额，输入密码时，不显示真实值，修改密码时显示真实值。-simulated bank teller card operation, a registered member of the eight to conduct inquiries, withdrawals, deposits, change passwords operation. Inquiries need to enter a password, the password to six. When the median and the corresponding password-meet, showed the card balance, otherwise the wrong password three times, the end of operation. Teller also need to enter the password, the password to six. When the median and password are consistent with the corresponding position, shows that the existing balance of the amount imported withdrawals, the remaining operation ended shows the amount, otherwise the wrong password three times, the end of operation. Limit daily total amount of desirable, if irregularities are given corresponding warning. ATM withdrawals

本例载波频率为20KHz，或载波周期为50μs。DSP晶振10MHz，内部4倍频，时钟频率为40MHz，计数周期为25ns。假设调制波频率由外部输入（1～50Hz），并转换成合适的格式（本例为Q4格式）。调制系数M为0～0.9。死区时间1.6μs。最小删除脉宽3μs。 主程序的工作是根据输入的调制波频率计算N、2N和M值。 -Example for the carrier frequency 20KHz, or carrier period is 50μs. DSP crystal 10MHz, internal 4 multiplier, the clock frequency of 40MHz, counting cycle 25ns. Assuming wave frequency modulation by external input (1 ~ 50Hz), and converted into an appropriate format (in this case for Q4 format). Modulation coefficient M is 0 ~ 0.9. Dead time 1.6μs. Delete the smallest pulse width 3μs. The work of the main program is based on input frequency modulation wave calculation of N, 2N and M values.
