There are several widely used methods to acquire the frequency response graph , including single tone method , multiple tone method , noise impulse method and maximum length sequence signal impulse method 分析音頻設(shè)備的頻率響應(yīng)特性主要有單音信號(hào)檢測法、噪聲沖擊檢測法和最大長度序列檢測法等。
4 . pulse signal is researched when amplified by edfa . for signal with a frequency of 10 khz , the gain is about 3db higher than sequence signal amplification , but in time domain , aberrance occurred with the amplified signal 4 .建立了edfa非穩(wěn)態(tài)放大模型,對(duì)頻率為10khz的脈沖信號(hào)進(jìn)行了實(shí)驗(yàn)分析,結(jié)果表明,其小信號(hào)增益比連續(xù)光放大提高了3db ,但輸出脈沖存在畸變。
