摘要： The present invention provides a circuit arrangement and technique for detecting any of a plurality of positions of a multi-position switch using a single input pin of a digital input/output device. Two specific embodiments are described relating to the use of a multi-position switch using a single digital input/output (DIO). In the first embodiment, a multi-position switch switches between various clock signals (e.g., pre-existing clock signals) on a circuit board, and inputs the same to the relevant pin of the. DIO device. In a variation of this embodiment, a second multi-position switch is connected in series with the first multi-position switch and varies the selected signal in a detectable and distinguishable way, e.g., by inverting or not inverting the signal selected by the first multi-position switch. In another embodiment, a multi-position switch switches between nodes of a series chain of resistors to produce a change to an RC circuit that will respond differently to a step change to the input depending upon the position of the multi-position switch. In either case, the positions of a multi-position (i.e., at least two position) switch can be detected using only one input pin of a digital input/output device.

摘要： A method and apparatus are disclosed for tuning a voltage controlled oscillator (VCO) having two point modulation used in a phase lock loop modulation system. A loop correction voltage applied to a first modulation input of the VCO when a first modulation signal, e.g., +1, is applied to a second modulation input of the VCO is compared to a loop correction voltage applied to the first modulation input when a second modulation signal, e.g., −1, is applied to the second modulation input of the VCO. The comparison produces a correction signal used to adjust the signal level of at least one of the signals, e.g., the second modulation input signal, applied to the two modulation inputs of the VCO.

摘要： A data-pattern feedback mechanism is introduced into the peak detection process of an automatic frequency compensation system in a Gaussian Frequency Shift Keying (GFSK) modulated system, providing fast and accurate fine-stage automatic frequency compensation (AFC). Maximum positive and negative peak registers are updated with new values as necessary based on detection during a sequence of identical binary bit values (e.g., during a “00” for detection of maximum negative peak frequency, or during a “11” for detection of maximum positive peak frequency), in a particular data frame. As soon as an initial value is determined for both the maximum positive and negative peak frequencies (e.g., after the first occurrence of a “11” and a “00”, in any order), fine-stage automatic frequency compensation can be initiated. Subsequent adjustments to the VCO of the local oscillator will further refine the frequency offset towards the ideal of zero. Quick determination of the maximum positive and negative peak frequencies is made based on data pattern feedback in accordance with the principles of the present invention, allowing for a fast and accurate fine-stage automatic frequency compensation adjustment of a local oscillation clock signal.
