The 14-bit LTC2351-14 is a 1.5Msps, low power SARADC with six simultaneously sampled differential inputchannels. It operates from a single ...
Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non...
ANALOG INPUT BANDWIDTH is a measure of the frequencyat which the reconstructed output fundamental drops3 dB below its low frequency value for a full s...
分析了調(diào)幅信號和載波信號之間的相位差與調(diào)制信號的極性的對應(yīng)關(guān)系,得出了相敏檢波電路輸出電壓的極性與調(diào)制信號的極性有對應(yīng)關(guān)系的結(jié)論。為了驗證相敏檢波電路的這一特性,給出3 個電路方案,分別選用理想元件和實際元件,采用Multisim 對其進(jìn)行仿真實驗,直觀形象地演示了相敏檢波電路的鑒相特性,是傳統(tǒng)的實...
