Design a Moore-type circuit for the pattern recognizer specified below. Show its (1) state diagram, (2) excitation table, (3) K-maps, (4) circuit diagram. A pattern recognizer with a 1-bit output Y accepts a 1-bit input X. Y becomes 1 only if the 1-0-1 pattern is seen at X. The circuit treats the incoming bit stream as overlapping sequences, i.e. the last bit of a previous sequence becomes the first bit of the next sequence. In effect, the circuit looks like the most recent three bits to check against the pattern, like below: X 0010101110100101011 Y 0000101000100001010

Consider a special purpose decoder that is called BCD to seven-segment decoder. The decoder takes a 4-bit Binary Coded Decimal (BCD) number X3 X2 X4 X0 (0-9) and produces 7 outputs a, b, c, d, e, f, and g The specification of this circuit is as follows: ⚫ The 7 outputs of the decoder are connected to LED segments as shown in the figure below. The LEDs are active low, ie, the LED emits light when it is connected to logic 0. • The decoder output is determined in a way so that the LED segments display the decimal representation of the input. For example, if the input X3 X2 X1 X0 is 0001 respectively (which is equivalent to decimal 1), the outputs a, b, c, d, e, f, and gare 1001111 showing the letter 1 on the display (remember the LEDs are active low).
