Basic concepts of wavelet and filter design. Bioorthogonal wavelet filter decomposition and reconstruction process. Design and application of a biorthogonal multi-wavelet filter.
Today I did some ADC external voltage sampling, sampling a single 1.5V Huatai battery. The voltage measured by the multimeter was 1677 mV, and the result measured by LM3S9B92 was 1637 mV. This result
I was on a business trip a few days ago. Today, I received a parcel from my colleague. When I opened the package, the small board made me excited. What made me even more happy was a letter to a friend
[size=4]F206 has three independent storage spaces for program, data and I/O, each of which is 64K×16 bits, of which the on-chip dual-access RAM is 544 words (288 words for data, and the other 256 word
Since the dynamic mathematical model of the asynchronous motor is a high-order, nonlinear, strongly coupled multivariable system. In the 1970s, Siemens engineer F. Blaschke first proposed the asynchro
With the development of the Internet of Things, the embedded processing field increasingly needs powerful digital signal processing capabilities. ARM has launched the ARM Cortex-M7 based on the origin
A while ago, I saw a smart bracelet on PDD for less than 10 yuan, so I bought one and planned to disassemble it for analysis. However, due to time constraints, I never did it, and finally took the tim
