Roff. I agree with you. As we can see in the signals from the Scope, with the voltage divider (Resistors 1kOhm and 9.1 kOhm) the amplitude of the signal is lowered, but the noise amplitude remains unchanged, i do not know why. My scope probe is connected to ground as you mentioned.
Roff. The problem with the phase shifting is that the controller needs to take instant actions within a closed loop for a given disturbance on the signal VL at the system output. A phase shifting would mean a delay in the action control from the processor. Anyway i will analyse deeper this...
Hello Everybody !
Thank you very much for your replies. In order to clarify more the situation, i have attached 2 files with the System Scheme and the signals obtained. I need to clean the noise from the Vad waveform to the A/D conversor. On Low Voltage system, it is a common...
Hello Everybody, i need some help.
I am working with an inverter prototype which generates a waveform as indicated with red color on file attached. I need to supply the rectified output of this waveform in a low voltage level (2 Volts) to the A/D conversor input of a PIC processor. Due to...
