a exemplifies the received signal as it leaves receiver 18 crosstalk distorts the signal as it propagates through the various receive path components fig3 b exemplifies the received signal as it is sensed by the adc 56 it will be understood that the waveforms of fig3 a and 3b as well as fig3 d and 3e are simplified for purposes of explaining the preferred embodiments relative amplitudes as well as the crosstalk components shown are not necessarily those seen in an actual device but are provided to simplify the description the phase reversal element 58 and its operation in correcting crosstalk will now be discussed in detail the programmable phase control element 60 is preferably included in dsp 51 and provides control for the phase reversal element 58 this control is robust in that it may power down the phase reversal element 58 and or it may cause the phase reversal element to cycle between phase states for example the programmable phase control element 60 may produce a pulse width modulated control signal as shown in fig3 c which when applied to the phase reversal element 58 either couples the signal received from the receiver 18 or a phase reversed version as shown in fig3 d the coupled signal from the phase reversal element would then be subject to the typical noise and crosstalk as would be introduced in the receive path between the output of the phase reversal element 58 and the input of dsp 51 as shown in fig3 e moreover the phase reversal element 58 provides subsequent phase cycles to dsp.
