The input x(t) and the output y(t) of a continuous- time system are related as $$y\left( t \right) = \int\limits_{t - T}^t {x\left( u \right)du} $$ The system is Which of the following is false for a thyristor? 1. Thyristor is a majority-carrier device. 2. The forward-bias portion of thyristor's i-v characteristics has two stable operating regions. 3. The forward-bias portion of thyristor's i-v characteristics has one stable operating region. 4. The negative gate current turns off the thyristor. Point on the satellite obits closest to the earth. The most useful transducer for displacement sensing with excellent sensitivity, linearity and resolution is Consider the following statements regarding the Moore and Mealy models: 1. In the Mealy circuit, the final output depends only on the present state of memory elements. 2. In the Moore circuit, output can change in between the clock edges if the external inputs change. 3. The implementation of a logic function in Mealy circuit needs more number of states than Moore circuit. Which of the above statements are not correct?
