解析：_lock_acquire(&s_ctx.mutex);：这行代码的目的是获取名为s_ctx.mutex的互斥锁，其作用是在初始化过程中确保只有一个线程能够访问特定的代码块。s_ctx.units[init_config->unit_id] = unit;：这行代码将unit指针存储在s_ctx.units数组中，数组的索引由init_config->unit_id确定。这意味着根据初始化...
Note that the AD876 must acquire a full-scale change in input voltage each conversion; this condition places the most severe demands on the AD8011, since it must supply the maximum amount of charge each conversion period. The AD8011 cannot supply the difference in charge instantaneously, so ...
The key challenge for optical transceivers is to acquire and process wider bandwidth signals or multiplex a number of input channels at lower power in a smaller footprint. The size, power, and cost structure of today's transceivers originally designed for long haul applications limit their ...
However, when I uncomment the above line of code that checks for data availability, l can never acquire an A/D reading. What are the known reasons that API *fIsDataAvailable() will always return 'no data available'? Thanks much in advance, --DJR Like 978 0 对...
Exit application 5.4 ECG acquisition This example shows how to use the 16-bit SDADC to acquire a human ECG using two ECG electrodes TS1 and TS2 that are installed on the STM32373C-EVAL evaluation board. The application source code is available in the file Project\STM32373C-EVAL\src\...

(the preferred input-tone amplitude is -0.5dB to -1dB FS), measure the response, and then acquire and measure the amplitude of the largest spurious component. SFDR is the ratio of the first to the second measurement. SFDR can also be determined by inspecting the FFT spectrum (plot) of ...
