Draw block diagram of digital LCR –Q meter and explain its working.
Block diagram
Working
The output of LCR-Q meter is given to current to voltage converter, AC amplifier or DC amplifer depending upon position of switch
Current to voltage converter converts current into voltage , the output is given to amplifer.
Ac amplifier amplifies analog input and then it is given to ac to dc converter .
The ouput of dc amplifier is given to A/D converter.
A/D converter converts analog signal into digital output andfinaaly displayed on display.
