A capacitor bias unit includes a first path (26) having a first impedance (29) and a second path (27) having a low impedance and a switch (31) connected between a voltage reference source and a capacitor (23). The capacitor can either be subjected to normal charge characterisitics or quick charge by closing the switch (31). Maintaining an appropriately charged state on the capacitor (23) aids in preventing netting error voltage steps from introducing DC component signals that adversely effect proper decoding and reception of demodulated data.
