Description: 基于matlab的DTMF仿真
DTMF为行频和列频（697Hz 770Hz 852Hz 941Hz 1209Hz 1336Hz 1477Hz 1633Hz）组合代表按键输入，使用以下公式可计算出行频和列频，从而确定按键编码：
vk(n) = 2*coef*vk(n-1) - vk(n-2) + x(n)
y(N)*y(N) = vk(N)*vk(N) - 2*coef*vk(N)*vk(N-1) + vk(N-1)*vk(N-1)-禄脵脫脷matlab渭脛DTMF 脗脮忙DTMF脦 陋 脨脨脝渭 潞 脥脕脨脝渭 拢 篓 697Hz 770Hz 852Hz 941Hz 1209Hz 1336Hz 1477Hz 1633Hz 拢 漏 脳 茅 潞 脧
