摘要:
The correlation and demodulation circuit (6) in particular for a pseudo-random code radio-frequency signal receiver (1) includes a correlation stage (7) connected to a microprocessor (12) in particular for configuring the correlation stage in normal operating mode or in test mode. In normal operation the stage receives intermediate signals (IF) corresponding to the radio-frequency signals shaped in means (3) for receiving the modulated signals from the receiver. The intermediate signals are correlated in a correlator control loop (8) of said correlation stage (7) with a replica of the first code supplied by a code generator (25). The code generator (25) is adapted via a microprocessor (12) to generate a replica of a pseudo-random code of shorter repetition length than the pseudo-random code of the radio-frequency signals. Intermediate test signals (IFtest) with a reduced pseudo-random code are supplied to the correlation stage (7) so as to perform a test representative of the correlation stage in closed loop operation more quickly than with conventional intermediate signals.

The portable device (10) is used for determining horizontal and vertical positions. It includes a pressure sensor altimeter (15) calibrated to a predetermined initial altitude, a GPS signal receiver (12) arranged to receive, via an antenna (11), signals originating from several satellites (20) in order to calculate position data of the device, a processing unit (14) receiving the position data from the receiver (12) and an altitude value from the altimeter (15), and display means (16) for the horizontal and vertical positions of the device processed and provided by the processing unit. The processing unit sends the GPS receiver a signal corresponding to the altitude value of the calibrated altimeter to enable the receiver to determine, using the altitude value, the position data of the device. A memory (13) including cartographic data and associated with the GPS receiver (12) can provide the precise data to the processing unit (14) in particular for calibrating the altimeter.
摘要:
The numerically controlled oscillator (8) is mounted in particular in a radiofrequency signal receiver which further includes means (3) for receiving and shaping the radiofrequency signals, a correlation stage (4) and a clock signal generator. The oscillator receives at one input a clock signal with a first frequency (CLK) which clocks the oscillator operations, and a binary word of several bits (Nb) to provide at one output at least an output signal (Mb) with a frequency determined as a function of said binary word and the clock signal. The oscillator includes a first accumulation stage (12) for a first number of most-significant bits (Ob) of the binary word and a second accumulation stage (12) for a second number of least-significant bits (Pb) of said binary word. The first accumulation stage is clocked at the first clock frequency (CLK) to supply the determined frequency output signal (Mb), while the second stage is clocked at a second clock frequency (CLK/N) N times lower than the first clock frequency. Output bits (Qb) or binary signals from the second stage are multiplied by N to be introduced at the input of the first stage every N cycles of the clock signal at the first frequency (CLK).
摘要:
An angular speed measuring device includes an oscillator for producing an excitation signal which induces mechanical vibrations in a rotating tuning fork, and an analog processing circuit for processing an electrical detection signal derived from the tuning fork. The analog processing circuit comprises a temperature-independent phase shifter responsive to the excitation signal for producing two signals in quadrature. The quadrature signals are applied to two multipliers which also receive the detection signal. The output signals from the multipliers are dependent on the fixed phase shift .phi. between the excitation signal and the detection signal, which is fixed for a given tuning fork, and on the variable phase shift .psi. which is a function of the rotational speed of the tuning fork, but the multiplier output signals are independent of temperature. After A/D conversion, the multiplier output signals are processed in a microprocessor to determine the angular speed.
