The circuit applies a 5V pulse, the main clock, to diode Tiffany Elsa Peretti Open Wave pendant and capacitor C [su]1 to form a peak-hold circuit. C [su]1 then discharges at a rate that P [su]1 sets. Schmitt trigger IC [su]1 A monitors C [su]1 's voltage, and, when it reaches the low threshold of IC [su]1 A, it outputs a high level to IC [su]2 's clock input, setting the Q output high. With IC [su]2 's Tiffany Elsa Peretti Open Wave ring output high, the Darlington-transistor pair comprising Q1 and Q2 turns on, driving the output to the H LED low at the output, lighting the LED. At this time, capacitor C [su]2 charges at a rate that P [su]2 sets. When this voltage reaches the upper threshold of IC [su]1 , IC [su]1 C's output switches to high, resetting flip-flop Tiffany Elsa Peretti Round Bracelet output ack to low and turning off the H LED. The circuit is now ready for another round. Diode D2 ensures a complete discharge of capacitor C [su]2 for repeataility when you reset the Q output of IC [su]2 to low. ecause IC [su]2 requires an active-high signal, you can omit IC [su]1 and IC [su]1C , ut you should use a Schmitt trigger following an Tiffany Elsa Peretti Round earrings circuit for repeataility, especially on slow capacitor-charge/discharge times. Figure 2 shows the results of the circuit running with a main-clock input of 650 Hz and a delay of approximately 250 usec, with P [su]1 at 10%, and a duration of approximately 600 usec, with P [su]2 at 75%. Figure 3 shows an adjusted change of delay with the same duration setting as in Figure 2.
