    摘要： A method and system for digital spur cancellation may include removing a spur in a left channel minus right channel (L−R) baseband signal generated from a FM signal. The L−R baseband signal may be generated by demodulating a sub-carrier, for example, by using CORDIC algorithm, in a signal demodulated from the FM signal. An orthogonal signal may also be generated by demodulating a sub-carrier, for example, by using CORDIC algorithm, in a signal demodulated from the FM signal. The phase of the orthogonal signal may be further adjusted to introduce a substantially −90° phase shift to spurs at a specific frequency. Accordingly, the spurs in the L−R baseband signal may be cancelled when the first L−R baseband signal is combined with the phase adjusted orthogonal signal.

    摘要： A method for calibrating a filter begins with the filter filtering a first signal having a first frequency to produce a first filtered signal, wherein the first frequency is in a known pass region of the filter. The processing continues by measuring signal strength of the first filtered signal to produce a first measured signal strength. The processing continues with the filter filtering a second signal having a second frequency to produce a second filtered signal, wherein the second frequency is at a desired corner frequency of the filter. The processing continues by measuring signal strength of the second filtered signal to produce a second measured signal strength. The processing continues by comparing the first measured signal strength with the second measured signal strength to determine whether the filter has attenuated the second signal by a desired attenuation value with respect to the first signal. The processing continues by adjusting filter response of the filter to produce an adjusted filter response when the filter has not attenuated the second signal by the desired attenuation value with respect to the first signal.

    摘要： A method for calibrating a phase locked loop (PLL) includes an open loop test and a closed loop test. The open loop test includes providing an optimal control input to a controlled oscillator (CO) of the PLL; determining rate of output oscillation of the CO based on the optimal control input; comparing the rate of the output oscillation with rate of an optimal output oscillation; and when the comparing the rate of the output oscillation with rate of the optimal output oscillation is unfavorable, adjusting an oscillation point of the CO until the comparing is favorable to produce an open-loop adjusted CO oscillation point. The close loop test includes determining a closed-loop input control level of the CO at the open-loop adjusted CO oscillation point; comparing the closed-loop input control level with the optimal control input; and when the comparing the closed-loop input control level with the optimal control input is not favorable, adjusting the open-loop adjusted CO oscillation point until the comparing is favorable.

    摘要： A method for determining attenuation of a transmit/receive switch for attenuating inbound RF signals begins by enabling the transmit/receive switch to provide a loop back configuration between a transmitter section and a receiver section of a radio frequency integrated circuit. When the transmit section provides a test RF signal to the receiver section the processing continues when the receiver section measures the signal strength of the test RF signal to produce a 1st signal strength. The processing continues by enabling receive attenuation mode of the transmit/receive switch. The processing continues when the transmit section provides another test RF signal to the receiver section via the transmit/receive switch in the receive attenuation mode to produce an attenuated test RF signal. The processing continues when the receive section measures the signal strength of the attenuated test RF signal to produce a 2nd signal strength. The processing continues when the 1st signal strength is compared with the 2nd signal strength to determine the attenuation of the transmit/receive switch.
