The truth table of a monoshot shown in the figure is given in the table below.
Two monoshots, one positive edge triggered and other negative edge triggered, are connected as shown in the figure. The pulse widths of the two monoshot outputs, Q1 and Q2. are TON1 and TON2 respectively.
The frequency and the duty cycle of the signal at Q1 will respectively be
-
-
ƒ = 1 , D = 1 TON2 + TON2 5 -
ƒ = 1 , D = TON2 TON1 + TON2 TON1 + TON2 -
ƒ = 1 , D = TON1 TON1 TON1 + TON2 -
ƒ = 1 , D = TON1 TON2 TON1 + TON2
-
Correct Option: B
From question,
| ƒ = | , D = | ||
| TON1 + TON2 | TON1 + TON2 |
