技術說明

於訊號分析，需要即時來偵測出波峰或波谷點時，僅需儲存所欲判斷之資料點(含時間與資訊大小)，以及其前後兩筆之資料，亦即在即時偵測中，最近所發生之三筆資料點。再加上利用輔助之儲存結構，如：堆疊或陣列等，來存放欲偵測時段內之確定波峰與波谷點，並用來與先前算判斷之可能波峰與波谷點合併或消除，且於確定為波峰與波谷點後再度存入該結構內。此方法，因不須考慮在平頭波峰或平頭波谷的狀況下，需要儲存不可預知之資料點數來進行判斷所，而造成無法真正達到即時偵測的實現。所此本方法，對於即時之偵測是真正可被實現的。 In signal processing, when the detection of peaks and valleys of the signals are required, this method requires only the interested instance of data point (including time stamp and signal value), as well as its previous and next instance of data, i.e. the latest three pieces of measured data points in real time. With the assistance of certain data structure for storage, such as stack, or array, to store the confirmed peaks and valleys of the signals in interested time period. Previous detected potential peaks and valleys of the signals were also stored in that data structure and could be retrieved to cancel or merge with the current potential peak of valley of the signal. The confirmed peak or valley point is stored back to that data structure again after the processing. This method can avoid the requirements of storing unknown number of data points due to the case of flat peak and valley situation, such that the detection of peaks and valleys of signals cannot be implemented in real-time. However, for this method, it is implementable in a real-time detection.
