Let’s start with the simple ones.1. The program first performs HWREG(SYSCTL_MWRALLOW) = 0xA5A5A5A5; because // 0xA5A5A5A5 must be written before some registers protected by MWRALLOW can be rewrittenFo...
Whether it is a traditional spectrum analyzer using analog IF processing or a modern spectrum analyzer using digital IF processing, both are swept frequency architectures that implement RF swept frequ...
Yesterday I designed an IIR filter and wrote a test program: the filter is a low-pass filter, which is required to filter out the frequency band above 20KHZ. The program is as follows: #include "filte...
