Time-windowed sample-and-hold
WebThe objective of the sample and hold circuit is to sample the unknown analog signal and hold that sample while the ADC decodes the digital equivalent output. The sample and hold circuit must: 1.) Have the accuracy required for the ADC resolution, i.e. accuracy = 100% 2N 2.) The sample and hold circuit must be fast enough to work in a two-phase ... WebDefinition: The Sample and Hold circui t is an electronic circuit which creates the samples of voltage given to it as input, and after that, it holds these samples for the definite time. The …

WebAlthough, the test conditions (f SAMPLE = 82MHz and N RECORD = 8192) were chosen to be identical with those in Figure 1, f IN was changed to 25.2245000MHz in Figure 2. Such a minor change in frequency offsets N WINDOW to an even number (2520), which clearly violates the rules for coherent sampling and causes spectral leakage. WebPSoC® Creator™ Component Datasheet Sample/Track and Hold Component Document Number: 001-80802 Rev. *A Page 3 of 10 The Track and Hold mode samples the signal on the falling edge of the sample clock, but tracks the input signal while the sample clock remains low.
