ABSTRACT:
Apparatus for sampling a repetitive input signal includes a sampling bridge responsive to a sampling strobe for sampling the input signal at an equivalent time point during its cycle, an error-sampled feedback loop for providing a sampling loop output representative of the input signal sample amplitude by determining and storing the difference between the input signal sample and the attenuated loop output, and a timebase circuit for generating the sampling strobe. The timebase circuit includes a circuit for repeating the sampling strobe at least twice at each equivalent time point during succesive cycles of the input signal for reduction of errors in the sampling loop output.
