As we have generally slow changing DATA signals i.e. DATA signals have slow rising and falling edges. And use of these signals creates problems in the working of Digital circuits. Hence to avoid these problems we use SCHMITT TRIGGER to sharpen up the edges of DATA. The transfer characteristics of this trigger are as follow: […]

555 Timer: Monostable operation
In monostable operation we have only one state stable and other state unstable. We have a input named Trigger to the 555 Timer. When we give no trigger timer stays in the stable state but when we give trigger then timer goes to the other state for a fixed time period and then goes back to the […]
Timing Circuits: Introduction
The timing circuits are the special purpose circuits which are generally used in digital circuits. We have the following important types of timing circuits: 1. 555 Timers are used in timing circuits very often as they are more reliable and lost cost. We have the two modes of operation of 555 Timer: Monostable operation Astable […]
