Abstract
PURPOSE: To obtain the sampling output of the signal to be measured which has been removed of DC component by generating different voltage values at each synhronization in correspondence to the ramp signal synchronized to the signal to be measured in an oscilloscope having a sample device or the like.
CONSTITUTION: A synchronizing circuit 3 generates the ramp signal starting signal synchronized to the signal to be measured a to cause the ramp signal to be outputted from a ramp signal generating circuit 4. A signal extraction and operation control circuit 5 generates different voltage values at each period in correspondence to the ramp signal and applies the same as sampling time control signals together with the ramp signal to a comparator 6, causing the sampling pulses of different sampling times to be generated at each period of the signal a from a sampling pulse generating circuit 7. The sampling pulses are supplied to a sampling gate and holding circuit 8 and likewise the signal to be measured being supplied to the circuit 8 is samplied at varying times at each period. The voltage difference between arbitrary two points in the waveform of the signal to be measured having undergone AD conversion is operated by an arithmetic circuit 10, hence the output c having been removed of DC component is obtained.
