Patent JP-H01241250-A (JP)
Title: Reception signal processing system
Inventor: KAKO TAKASHI
IPC: H04L27/233
Filed: 1988-03-22
Abstract: PURPOSE:To suppress phase jitter at high frequency by using a baud rate frequency or a sampling frequency higher than the baud rate frequency so as to process a base band signal. CONSTITUTION:An interpolator filter 7 uses decided result decided by a deciding circuit 3, thereby generating a reference sampling frequency. For example, an impulse reply signal is outputted by using the decided result of the circuit 3 as an input signal and the output signal is set so as to be a sampling signal having the integer multiple of the baud rate frequency. Thus, an error signal between the sampling signal being the generated reference and a base band signal inputted to the circuit 3 is detected as shown in figure and the error signal   is fed back to the equalizer 1 and the carrier phase controller 2 so as to be zero. Thus, the filter 7 is provided to increase the sampling frequency even with a narrow band so as to suppress phase jitter, thereby transmitting a data at higher speed.

Patent JP-H1138118-A (JP)
Title: Method for reducing excessive spectral power distribution by class-c saturation amplification of pulse carrier signal
Inventor: KUMAR MAHESH
IPC: H03F3/217
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce the spectral power distribution when a pulsed carrier signal is amplified by modulating a pulsed sine signal inputted to a class-C saturation amplifier after correcting a rectangular envelope to a trapezoid envelope and, at the same time, by using a filter which reduces the spectral energy in a band other than the passing band. SOLUTION: Each amplifier 26 is provided with an amplifier channel 28 incorporating a pair of push-pull class-C saturation amplifier elements 30. A first band-pass filter 34 corrects the nearly rectangular envelope of a signal pulse outputted from a signal source 22 by transforming the envelope into a trapezoid envelope. Since most of the cycle of a sine waveform in the rising and falling parts of the waveform is saturated by the output of an amplifier stage, a second filter 36 is inserted so as to restore the trapezoid envelope. The output signal of the filter 36 becomes a sine wave which does not reach a saturation level even after the signal pulse is amplified by means of the amplifier 28. Therefore, no excessive spectral power distribution exists in the signal outputted from a terminal F.

Since the layer 2 and the layer 5 superposed on the layer 2 with the ink are provided on the surface of a sealing or signature column, it becomes difficult to distinguish the patterns of the layers 2, and 5 because the ink is invisible. Thus, decision of truth or falsehood is facilitated due to vanishing of the ink at the time of falsification after a signature.
