摘要: An apparatus for adaptively checking document thickness is provided, the apparatus having a transducer which senses a variation in the thickness of a document passing through a paper transport. Each new document thickness as indicated by the transducer is compared with a window established by the preceding document thickness. If the thickness of the current document meets prescribed limits as established by the preceding document, a memory element is updated to correspond to the thickness of the current document. Should the document thickness compare unfavorably with the window, an alarm signal is generated and the process halted without refreshing the memory element.

摘要: A TTL (transistor-transistor-logic) compatible voltage controllable crystal digital clock having a relatively wide linear frequency control range with relatively small control voltage range. A quartz crystal in series with a voltage variable reactance is coupled in a regenerative loop of an oscillator circuit. A control voltage varies the capacitance of the voltage variable reactance resulting in a phase shift around the regenerative loop and changing the frequency of oscillation of the circuit.

摘要: A special purpose computer for correcting phase jitter of a communication channel. The computer performs a predetermined algorithm for estimating the phase jitter of the communication system and delaying the data signals so that their delay is equal to the carrier phase estimation delay at the point where the final carrier phase correction is applied.

摘要: An FSK transmitter includes a crystal controlled generator which includes a counter which when cycled provides a number of output signals which are logically combined to produce pulse waveforms having different repetition frequencies. The generator counter is arranged to be cycled in accordance with the state of bilevel signals applied to a plurality of input selection lines to apply pulse waveforms of the appropriate repetition frequencies to an output circuit for transmission over a communications channel. The transmitter further includes a ramp generator which is synchronized with cycling of the crystal controlled generator and which is also operative in response to the state of input selection lines to produce pulse waveforms whose repetition frequencies approximate those produced by the crystal controlled generator. During a shift in frequency, the transmitter uses the ramp generator waveforms to establish the cycle time of the counter so as to provide a nominal time period for the pulse waveforms being applied to the output circuit during the time of frequency shift thereby minimizing distortion of the waveforms at the time of crossover.
摘要翻译: FSK发射机包括晶体控制发生器,其包括计数器,当循环时,计数器提供多个逻辑组合的输出信号,以产生具有不同重复频率的脉冲波形。 发生器计数器被布置成根据施加到多个输入选择线的双电平信号的状态循环,以将适当重复频率的脉冲波形施加到输出电路,以在通信信道上传输。 变送器还包括与晶体控制的发生器的循环同步的斜坡发生器,并且响应于输入选择线的状态产生脉冲波形,其脉冲波形的重复频率接近由晶体控制的发生器产生的脉冲波形。 在频率偏移期间,发射机使用斜坡发生器波形来建立计数器的周期时间,以便在频率偏移期间为施加到输出电路的脉冲波形提供标称时间间隔,从而最小化 交叉时的波形。
