Abstract: To improve the performance of the electronic devices. The designed logic circuit should be reliable. In design for digital logic circuts. Usually, only the stable logic relationship between inputs and outputs is considered. But the designed circuit may create glitches and persist indefinitly sometimes. Because the designer held transient characterstic out of no account. In this perpa practical method of descriminating glitches is proposed. This method which is called tendency value table is applied to some seguential logic circuits. Some discussed examples show that the tedency value method can discriminate glitches before the circuit is complete, so that that designed circuit is perfect.
