The signal system answer; The signal system answer was compiled by Yang Xiaofei and includes complete answers to the exercises. Exercise 1.1.4 (waveform omitted) 1.5, determine the zero value time interval of the following signals. (1) (2) (3) (4) (5) 1.6 Try to draw the expressions of the waveforms of various continuous signals shown in Figure 1-6. (a) (b) (c) (d) 1.13: ,.(1).(2).(3).(4). (5) .1.18. (1) even, even harmonics (2) even, odd harmonics (3) even, even and odd harmonics (not unique) (4) odd, odd harmonics (5) odd and even harmonics (6) odd, odd harmonics and even harmonics 1.19 Solution: (1) Organizing yields: (2) Organizing yields: 1.20 Solution: From the premise y(k)=y(k-1) αy(k-1)- βy(k-1) f(k)∴y(k)-(1-α- β)y(k-1)=f(k) 1.21 Solution: From the premise y(1)=f(1) βy(1) Y(2)=f(2) y(1) βy(1) The total principal and interest for the k-th month is y(k), and for the (k-1)th month it is y(k-1). So, the deposit at the beginning of the k-th month in the bank is Y(k)-(1-β)y(k-1)=f(k) 1.22 Solution: From the premise y(k)=y(k-1) Therefore, y(;" .. The description provided includes answers and solutions to various exercises related to signal systems. The answers cover a range of topics including waveforms, expressions of signals, harmonics, and calculations involving time intervals and deposits. The content appears to be structured and organized, presenting a comprehensive guide for understanding and solving problems related to signal systems.
