2) prevent electromagnetic energy along the transmission line reflections affect the stability of the output signal, adding the isolator, the circuit is more secure, but also played a role in shielding interference. (3) the use of DSP programming on the frequency and phase control, can produce a var

2) To prevent the electromagnetic wave energy transmission lines along the reflex effects of output signal isolator, stability, and joined the circuit more secure, it will also have a role in shielding interference. ( 3) using DSP programming control of frequency and phase-in, can generate multiple

2) prevented as a result of the electromagnetic wave energy along the transmission line reflection influence signal output stability, has joined the disconnector, causes the electric circuit to be safer, also played the shield disturbance role.(3) uses the DSP programming realization to the frequenc

2) prevention effects due to the reflection of electromagnetic wave energy along the transmission line signal output stability, has joined the isolator, make the circuit safer, shielding interference also plays a role. (3) use of DSP programming on the frequency and phase control, can produce a vari

2)Prevent because the electromagnetic wave energy influences the stability that the signal outputs along transmitting the reflection of the line, put into the isolator, make the circuit safer, has played a role in shielding the interference too. (3)Make use of DSP programming to realize the control
