Abstract

A ten microsecond (microns) magnetostrictive delay line 10 is used to assemble data received serially in an asynchronous manner on line 6. The data is established in delay 10 in the form of 1 micron s positive and negative pulses which represent binary 1 and 0, respectively. Data bits are received on line 6 at eleven microns intervals or greater. Single-shot 8 produces an eleven microns pulse width for any incoming pulse on line 6. Data can also be entered into the delay 10 in parallel on lines 14.

Data Compressor and Assembler

A ten microsecond (microns) magnetostrictive delay line 10 is used to assemble data received serially in an asynchronous manner on line 6. The data is established in delay 10 in the form of 1 micron s positive and negative pulses which represent binary 1 and 0, respectively. Data bits are received on line 6 at eleven microns intervals or greater. Single-shot 8 produces an eleven microns pulse width for any incoming pulse on line 6. Data can also be entered into the delay 10 in parallel on lines 14.

The output of delay 10 is recirculated through amplifier and shaper 16, line 18, Or 20, inhibitor 22, and Or 24. When a data bit appears at the output of delay 10 for recirculation, a data bit appearing on line 12 is blocked from entry by the de-conditioning of gate 26 via line 28.

If a data bit does not appear at the output of delay 10 and a data bit is on line 12, it is entered into the delay 10 in the proper bit position. Once every ten microns (time T) flip-flop 30 is set to condition gate 32. If, at the same time a data bit does not appear at the output of delay 10, a control pulse is applied to gate 32 via line 34 through the control pulse circuit 36 and inverter 38. Control 36 provides a unidirectional control pulse, if either a positive or negative pulse from amplifier and shaper circuit 16 is applied to it. The output of gate 32 activates a one microns single-shot 40. The output of single-shot 40 controls gate 26 permitting the da...
