Abstract

This is a magnetic core pulse counting circuit with an adjustable radix. It comprises quantizers 10 and 11 and pulse counter 12. The single shot feature is obtainable from the characteristics of quantizer 11. Each of a series of clock pulses applied to terminal 13 renders transistor 14 conductive. This action energizes drive winding 15 of quantizer 10 driving the core to saturation in a given direction. This produces a uniform volt second pulse in output winding 17, which is applied to drive winding 18 of core counter 12.

Single Shot Delay

This is a magnetic core pulse counting circuit with an adjustable radix. It comprises quantizers 10 and 11 and pulse counter 12. The single shot feature is obtainable from the characteristics of quantizer 11. Each of a series of clock pulses applied to terminal 13 renders transistor 14 conductive. This action energizes drive winding 15 of quantizer 10 driving the core to saturation in a given direction. This produces a uniform volt second pulse in output winding 17, which is applied to drive winding 18 of core counter 12.

The amplitude of the output pulse from 17 is varied by changing the winding taps by relay controlled contact points 19. Counter 12 is a variable radix counter in which the radix is adjusted by varying the resistance 20. This establishes the number of input pulses required to drive the magnetic core to saturation in a given direction. Once the core is driven to saturation, the next input pulse applied to drive winding 18 provides an output pulse on line 21. This triggers transistor 22 and drives quantizer 11 to saturation to provide an output pulse at terminal 23.

When counter 12 and quantizer 11 are reset by a pulse from reset pulse source 24, zero time is established. A single shot delay is generated when the counter 12 reaches saturation and fires the quantizer 11, thus generating after a predetermined delay time a pulse possessing millimicrosecond rise time characteristics. The delay time is adjusted and controlled by resist...
