摘要： A phase locked loop signal generator is especially adapted for synthesizing a selectable frequency signal for exciting an HF radio frequency transmitter to transmit over the seven marine telegraph bands. The signal generator includes an oscillator for providing a highly stable frequency standard. Another signal generator is responsive to the frequency standard and to frequency selector signals input by the operator for generating an exciter signal which is coupled to the transmitter for effecting the RF transmission within a predetermined frequency range. The exciter signal generator includes: a reference dividing circuit programmable in response to the frequency selector signals for providing a reference frequency signal having a frequency which is a fractional part of that of the frequency standard; a phase locked loop circuit having a frequency divider in the feedback loop which is responsive to the reference frequency signal for producing an intermediate signal having a frequency which is a multiple of that of the reference frequency signal; and an output divider circuit is coupled to the phase locked loop circuit and is responsive to the frequency selector signal for generating the exciter signal to be at a frequency which is a fractional value of that of the intermediate signal. By varying the frequency selector signal, over 5000 transmitting frequencies are available using a conventional harmonic-related transmitter.

摘要： A digital phase-locked loop consisting of a digital phase detector for detecting the phase differences between the output and the input frequency signals, a microprocessor programmed to perform both the functions of the loop filter and the phase shifter, and a binary rate multiplier to perform the function of voltage-to-frequency conversion is disclosed. A more precise frequency resolution is obtained by use of the binary rate multiplier and a further reduction in circuit complexity is achieved by removal of the phase shifter circuit in favor of the microprocessor programming.

摘要： A distributed processing telex switch having different levels of processor control to handle the calls between terminations connected to the exchange is disclosed. A common control processor occupies the highest level of processor control and function as the system-wide manager. Next below common control is a plurality of master control processors which function to switch the command data between common control and the lower levels of processor control, and to handle the conversation data generated by each of the terminations connected to the exchange. Each master control processor controls a predetermined number of termination from among all of the terminations connected to the exchange. Connected to each master control processor is a plurality of group control processors which control the flow of data to and from a second predetermined number of terminations from among the terminations controlled by each master control processor. The group control processors occupy the next lower level of processor control from the master control level. Associated with each group control processor is a line control processor that cooperates with its associated group control processors to produce the signaling sequences in the terminations and to handle the conversation data from and to the terminations. The line control processor occupy the lowest level of processor control.

摘要： A system for generating telex signaling sequences in each termination line in a group of customer termination is disclosed. The system includes a multi-line high-speed line control processor which transmits to and receives from each customer termination, data signals indicative of the signaling levels in the termination lines. The line control processor controls the termination signals by executing, in a time share mode, selected signaling routines for each termination. Connected between the line control processor and the customer terminations is a terminator controller means for selecting the termination currently being time share processed to input to or receive signals from the line control processor. Also connected to the line control processor is a group control processor which supervises the generation of the signaling sequences in each termination by executing script task routines. These script tasks routines cause the line control processor to execute the selected signaling routines to produce the signaling sequences required by each termination in the group.

摘要： A teletypewriter line keyer with a switching current regulator responsive to a floating, loop current powered voltage comparator used as a loop current monitor. The line keyer, which may have positive and negative line current keying, uses a single current monitor to control positive and negative current regulators responsive to the positive and negative keying respectively. The switching regulators operate within a relatively narrow band centered around the nominal signaling current, with filtering being provided for ripple control. The circuit may also include a keying detector and open loop detector for system monitoring.
