Discrete-Time Systems A discrete-time system processes a given input sequence x[] to generates an output sequencey[n] with more desirable properties In most applications, the discrete-time system is a single-input, single-output system:

一、Ⅱ幂级数: 10定义,具有下列形式的函数项级数 ∑anxn=a+a1x+a2x2+…+anxn+称为幂级数

Karnaugh maps It is a matrix of squares. each square represent a minterm or maxterm from a Boolean equaTion N-variable karnaugh map have 2 squares The binary numeral on the sides of k-map is the variable coordinates

1．△A=±50*0.5%=±0.25V △A/A01=±0.25/40=±0.625%△A/A02=±0.25/20=±1.25% 2．△A=±250*2.5%=±6.25V △A/A0=±6.25/U＜5% ∴U＞125V最小电压为 125V
