FACTS: In Module 3, you have learned about Op-Amps like Inverting and Non-Inverting Amplifier and many more, one of the topics in Module 3 is the Integrator and Differentiator. An operational amplifier (op-amp) integrator is an operational amplifier circuit that performs the mathematical operation of integration with respect to time-this means the output voltage is proportional to the input voltage integrated over time. A differentiator is an op amp-based circuit, whose output signal is proportional to the differentiation of the input signal. An op-amp differentiator is basically an inverting amplifier with a capacitor of suitable value at its input terminal. The electric potential of inverting terminal is also zero, as the opamp is ideal. QUESTION: Answer the ff. 1. What are the problems in an ordinary op-amp integrator? 2. Why op-amp integrator output is linear? 3. What are the problems in an ordinary op-amp differentiator? 4. What are the advantages of integrator and differentiator…

A sequential circuit has one input X and four outputs Z₁ Z₂ Z3 Z4. Z1 Z2 Z3 Z4 represents the gray code encoded number equal to the number of pairs of adjacent 1's that have been received as inputs. Use the gray code that is on page 22 of the textbook. For example, if the circuit had received 7 pairs of 1's as inputs, Z₁ Z2 Z3 Z4 = 1011. In addition, the circuit resets when the circuit receives 5 pairs of 1's. Find a Moore state graph and table for the circuit. Examples Input sequence: Output sequences: X = 1 0 1 1 1 0 0 1 1 0 1 1 0 1 0 1 1 10 Z₁ = 0 0 0 0 0 0000000000100 Z₂ 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 0 0 Z3 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 - Z4 = 0 0 0 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 X 11111111 Input sequence: Output sequences: Z₁ = 0 0 0 0 0 100 Z2 0 0 0 0 1 100 = Z3 = 0 0 1 1 1 1 0 0 Z4 0 1 1 0 0 0 0 1 =
