    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.
