adjustable square/wave edges

1. nt of the gate to takes for the voltage level at the i pu 1 at _ the equation; At+ = —R1 X C1 X UT+ In (1 — ---) adjustable square The ability to delay the leading and trailing edges of a square waveform will find many applications in digital circuits. The diagram in figure 1a shows that only a very few components are required to do UDD this.Thecircuitmakesusefathefactthattheout- lb put of a Schmitt trigger ge will not change state until the voltage level on the input reaches a certain critical point known as the trigger threshold. During a rising edge at the input, capacitor C1 is charged via D1 and R1. This increases the time it reach the trigger threshold point. With a logic the input to the circuit, the potential across C1 will continue to rise until, for all practical purposes, it reaches the supply voltage level. When the input returns to zero C1 will discharge via D2 and R2, again delaying the time at which the trigger thres- hold is reached. A clear understanding ca...
