Pulse-delay-with-dual-edge-trigger
A single monostable multivibrator delays a pulse train by a variable amount; however, this amount cannot be less than the minimum allowed pulse width. The exclusive-OR gate, IC1, generates a short pulse following every leading or falling edge of the input waveform. These pulses cause one-shot IC2 to produce a negative-going pulse with a duration equal to the desired time delay, which is set by adjusting potentiometer R. Flip-flop IC3 then creates a delayed replica of the input pulse by latching the Q1 output of IC2 between positive-going transitions. The output-pulse duration can be independently controlled by cascading a second one-shot with the first.
The circuit employs a monostable multivibrator configuration to achieve pulse delay functionality. The initial component, an exclusive-OR gate (IC1), is responsible for detecting transitions in the input waveform, generating a brief pulse for each leading and falling edge. This pulse serves as a trigger for the subsequent one-shot multivibrator (IC2), which is configured to produce a negative-going pulse. The duration of this pulse is determined by the setting of potentiometer R, allowing for adjustment of the time delay in the output signal.
The output from IC2 is then fed into a flip-flop (IC3), which captures the state of the pulse at the Q1 output. This configuration ensures that the output pulse is a delayed replica of the input signal, effectively latching the output during the positive-going transitions of the input pulse. This design allows for flexibility in pulse duration, as the output can be further modified by cascading an additional one-shot multivibrator. By connecting a second one-shot to the first, the output pulse duration becomes independently adjustable, providing the capability to tailor the timing characteristics of the circuit to specific applications.
This circuit finds applications in various timing and control systems, where precise pulse delays and durations are necessary, such as in digital communication systems, signal processing, and automated control systems. The ability to adjust the timing parameters enhances the versatility of the design, making it suitable for a wide range of electronic applications.A single monostable multivibrator delays a pulse train by a variable amount; nonetheless, this amount can be no less than the minimum allowed pulse width fw· The exclusive-OR gate, IC1, generates a short pulse following every leading or falling edge of the input waveform.
