摘要： A pair of input signals corresponding to X and Y coordinate information are processed and simultaneously applied at certain time intervals to a display system, and the points represented by said pair of input signals are successively connected by straight lines. In a first embodiment of the signal processing, wherein the input signals and digital signals, such input signals are applied to a first digital analog converter for converting the digital signals into related quantum analog voltages whereupon the quantum voltages are applied to a second digital analog converter which effectively adds the quantum voltages. The output of the second converter is impressed upon a CRT display of the oscilloscope or an XY recorder, thereby tracing a figure on the display or recorder. Alternatively, the first digital analog converter can be replaced by an analog attenuator for converting analog input signals into related analog quantum voltages which are then processed the same as in the above-mentioned first embodiment. Thus, very accurate coordinate presentations can be traced on a CRT display of the oscilloscope or an XY recorder.

摘要： A delay-line memory using a magnetostrictive delay-line, in which a pair of bidirectional pulses derived from the delay-line by the use of a magnetostrictive-electric transducer and having successive reverse polarities with respect to the successive polarities of a preceding bidirectional pulse are converted into a square wave output signal by a bistable circuit performing hysteresis switching action triggered at times when the instantaneous level of the bidirectional pulses exceeds a first reference level determined between the zero level and the plus peak level of the bidirectional pulses and descends a second reference level determined between the zero level and the minus peak level of the bidirectional pulses.
