Problem 2. Design a sequential circuit DETECTOR that has one input X and one input Y. The DETECTOR detects the sequence 110. If an input X is a "1", followed by another "1" followed by a "0" then the output Y is set to "1", otherwise Y is set to "0". (a) Design this circuit using D-type Flip-Flops (b) Repeat your design and this time use J-K-Flip Flops

An electric kettle is made out of stainless steel, weighs two pounds (when empty) and is equipped with a heating element that consumes 2 kw of electricity. assuming that the water and the kettle are at the same uniform temperature at any moment of time, calculate the shortest possible time to bring 2 quarts of water from room temperature to the onset of boiling
