摘要： A sample acquisition apparatus for sampling first and second signals within a signal processing arrangement, includes a sampler for capturing sections of the waveforms of both the first and second signals, a switch for alternating correction of the sampler to a point in the arrangement where said first signal can be sampled and a point in said arrangement where said second signal can be sampled. A timer for timing the operation of the switch causes the sampler to capture a first waveform section of the first signal and a second waveform section of the second signal, wherein the second signal is responsive to the first signal and the timing of the switch is such that the second section includes a portion that has been generated in response to the first section.

摘要： A method of controlling an amplifier, the method comprising a sampling step of using a sampler to obtain digital samples of both an output signal of said amplifier and a reference signal, a derivation step of obtaining from said samples values of a first parameter and associated values of a second parameter, an averaging step of averaging the first parameter values over ranges of the second parameter such that, for each range, an average of the first parameter is obtained by averaging the first parameter values whose associated second parameter values lie in the range, a generation step of generating a control signal for said amplifier from said averages, a suppression step of using said samples of said reference signal to inhibit the effect upon said control signal of errors in the operation of said sampler and a control step of applying the control signal to said amplifier to direct the operation of said amplifier. The invention also relates to apparatus involved in carrying out the method.
