ieee754_32
Converts a floating point value to IEEE 754 32 bit binary representation.
Sign Bit: 1
Exp: 2 to 9
Frac: 10:32
Single-precision floating-point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point. In IEEE 754-2008 the 32-bit base 2 format is officially referred to as binary32. It was called single in IEEE 754-1985. In older computers, other floating-point formats of 4 bytes were used.
For example, the 32-bit floating point bit pattern 1 01111101 00101100000000000000000 is interpreted as the following:
(− 1)1 × (1 + 0.34375) × 2(125–127) = -1.34375× 2− 2 = -0.3359375

ecg信号产生
模拟母亲心电信号，因为成人的正常心跳频率为60-100次/分，幅值范围为0.01-4mV，平均心率为80次/分，因此母亲心跳周期为0.75s，采样频率为350Hz，模拟胎儿心电信号，与上文中生成母亲心电的方法相似，不同的是胎儿的心跳频率为120-160次/分，平均心率为140次/分，因此心电周期大概为0.46s，并且胎儿心电的幅值比成年人的小很多，约为28-30μV。
