Signal processing apparatus and radio clockPROBLEM TO BE SOLVED: To provide a signal processor which can efficiently make data from a detection signal of a standard wave, and to provide a radio-controlled timepiece which can accurately decode a time code based on the data.佐野 貴司...
a band-pass filter and an amplitude limiter, the amplitude-limited signal having a subcarrier frequency is transformed into digital sampling values, if necessary by additional filtering, and the sampling values are supplied to at least one phase control loop for deriving a bit clock signal. ...
RADIO WAVE RECEIVER, RADIO CONTROLLED CLOCK, SIGNAL ACQUISITION METHOD, AND PROGRAM PROBLEM TO BE SOLVED: To avoid excessive power consumption while acquiring information needed for positioning more reliably.SOLUTION: A radio wave receiver pertaining to the present invention comprises: radio wave reception...
A signal is composed of sum of its in-phase (I) and Quadrature (Q) components. The data input to the SDR is complex, which includes I and Q signals. The Local sampling clock is used as the basic reference in Digital Signal Processing (DSP), therefore it relies heavily on I and Q ...
This way, you don't need to go without the convenience of radio signal-controlled precision. With a CASIO radio-controlled watch, there is no longer any need to set summer or winter time in many countries, because your watch does it all by itself. The most important international time ...
Since the D-STAR receiver in DSD is not yet optimized for GMSK reception, I have worked around this problem by doing the GMSK demodulation in GNU Radio (with a Clock Recovery MM and a Binary Slicer block), then re-modulating the signal before passing it on to DSD. This improves the ...
During the test, the receiver in light-indoor condition could autonomously track only one satellite, identified as PRN 9. This PRN was also tracked by the aiding user; therefore, it was used to estimate the clock offset among the two PCs. Based on the signal processing of PRN 9, the aidi...

Also, even if the actual ticking of the clock is reliable, one has to know if any outside influence has been able to move the hands of the clock beyond what the mechanism of the clock itself can achieve. Of course, this is where things get a little bit tricky…...
