§01 低频混沌信号

一、混沌电路信号

在 测试简单混沌电路系统的低频特性 测试了通过更改 两个晶体管组成的混沌电路 输出信号的频率。为了利用 计算机的声卡 能够更好地记录混沌信号，而不受 声卡的频率特性 的影响，降低混沌电路所产生的音频信号的频率范围，可以避免因为频率录制过程中欠采样所带来的问题。

1、电路及其参数

产生混沌信号的基本电路仍然使用在 双晶体管混沌电路 的基本电路，将其中的电容增加，从而降低混沌信号的基本频率。

（1）搭建实验电路

电路中电容：

C1：474
C2：474
C3：474
C4：154

为了避免计算机声卡输入电阻对于混沌电路影响，使用TLC082组成缓冲电路，对混沌电路中Q1的集电极，C1上的电压信号跟随缓冲之后通过两个屏蔽电缆接入计算机声卡的线路输入。通过调整计算机录音设备的线路输入增益，使得录音的时候信号不会过度饱和。

▲ 图1.1.1 带面包板上搭建的测试电路

（2）电路基本频率

调节R5，使得电路处在周期震荡状态，此时振荡频率为121Hz左右。

▲ 图1.1.2 基本周期震荡X-Y波形

2、录制混沌信号

（1）调整R5使得电路进入混沌振荡状态

通过调整R5 电位器，使得电路进入混沌震荡状态。利用Audacity软件录制该信号。

▲ 图1.1.3 Q1，C1电压的X-Y轨迹图

（2）使用AUDACITY软件录制混沌信号

下面是录制的两路音频信号的波形。

▲ 图1.1.4 录制的两路音频信号的波形

（3）录制一批混沌信号

调整R5，使得电路处在不同的振荡状态，然后录制一批普通的的混动信号。

序号	信号属性	文件名称	时长
1	混沌信号	CVLOW1	10s
2	混沌信号	CVLOW2	10s
3	混沌信号	CVLOW3	10s
4	周期信号	CVLOW4	10s
5	过渡信号，从周期过渡到混沌，再从混沌过渡到周期	CVLOW5	16
6	过渡信号，从周期过渡到混沌，再从混沌过渡到周期	CVLOW5	26

▲ 图1.1.5 录制的过度混沌信号

二、数据文件存储

将上述数据文件存储在Gitee软件仓库中：

▲ 图1.2.1 在Gitee中存储的混沌数据文件

Gitee中存储的混沌信号

※ 实验总结 ※

通过更换电路中的电容参数，进一步降低了混沌信号的中心频率，使用声卡进行记录的时候可以提高记录数据的完整性。
