%The phase locked loop(PLL),adjusts the phase of a local oscillator %w.r.t the incoming modulated signal.In this way,the phase of the %incoming signal is locked and the signal is demodulated.This scheme %is used in PM and FM as well. %We will implement it by using a closed loop system.Control systems %techniques are applied here.

以SPCE061A單片機(jī)為核心,通過DDS合成技術(shù)設(shè)計(jì)制作了一個(gè)步進(jìn)值能任意調(diào)節(jié)的多功能信號(hào)源。該信號(hào)源在1KHz~10MHz范圍能輸出穩(wěn)定可調(diào)的正弦波,并具有AM、FM、ASK和PSK等調(diào)制功能。信號(hào)輸出部分采用低損耗電流反饋型寬帶運(yùn)放作電壓放大,很好地解決了帶寬和帶負(fù)載能力的要求。系統(tǒng)帶中文顯示和鍵盤控制功能,操作簡便,實(shí)現(xiàn)效果良好。

VDSP++打開。This directory contains an example ADSP-BF537 RTC project that does a basic blink routine and then puts the part in deep sleep mode to be woken up from a RTC Stopwatch Event. Once woken up, the RTC is reconfigured to toggle the EZ KIT LEDs using RTC second, minute, hour, and day interrupts.
