一、频分制遥测系统的原理和框图频分制遥测系统的基本原理我们在前几节中都介绍过了,现在我们给出它的完整的方框图如图一。发射端每一路都有一个付载频调制振荡器,各路付载频振荡器的振荡频率是互相错开的,它们之间保持一定的间隔,防止付载频调制振荡器输出的已调频谱重迭。每一路付载频调制振荡器含有一个带通输出滤波器,用来消
First, the principle and block diagram of the system of frequency division telemetry The basic principle of frequency division telemetry system We have introduced in the previous sections, and now we give it a complete block diagram in Figure 1. The transmit end has a pay-band frequency modulation oscillator on each side. The oscillation frequencies of each of the pay-band frequency-division oscillators are staggered with each other to maintain a certain interval between them and prevent the modulated spectral outputs Diego Each channel contains a carrier frequency modulation output passband filter, used to eliminate
