Why do high-quality capacitors have polyethylene,polycarbonate,or Teflon dielectrics?
A)They minimize voltage variations resulting from capacitor characteristics.
B)They limit the maximum input frequency that the S/H circuit can accurately process.
C)They convert quantized waveforms into stepped analog signals.
D)They isolate the input signal from the S/H circuit and provide proper impedance matching.
