当突发信号带宽大于频谱分析仪带宽时，则需要采用频域积分法进行测量。在描述突发功率的频域积分法之前，先来看看频域积分法测量信号的信道功率或邻道功率。相对于信道带宽，频域积分法测量信道功率首先要选择十分小的分辨率带宽，典型值为信道带宽的1%～3%。频谱仪频宽略大于被测量的信号带宽，且至少要从信道的低端频率开始扫描到高端频率。测量的结果对应于在选择的信道带宽内测量电平的线性值的积分，所得的邻道功率dBc是相对于用户信道的功率。

D型控制方式中的微机ROM内，预先储存着以发动机转速和进气管内的压力为参数的的各种状态下的进气量，微机根据所测的各运转状态下的进气压力与转速，参照ROM所记忆的进气量，可以算出燃油量L型控制所用的空气流量计与一般工业流量传感器基本相同，但它能适应汽车的苛环境，但对踏油门时出现的流量的急剧变化的响应要求及在传感器前后进气歧管的形状引起的不均匀气流中也能高精度检测的要求。*初的电子燃油喷射控制系统的采用的不是微机。
