What should be done to find the initial values of the circuit variables in a first-order R-C circuit excited by only initial conditions?

What should be done to find the initial values of the circuit variables in a first-order R-C circuit excited by only initial conditions? Correct Answer To replace the operator by a voltage source

If a 1st order RC circuit excited by the initial conditions, then that means the capacitor is initially charged. Therefore, we can replace the capacitor by a voltage source with a voltage equal to the initial value of voltage across the capacitor.

Important Points:

  • If a 1st order RL circuit excited by the initial conditions, then we replace the inductor by a current source equal to the initial value of current flows in the inductor.
  • If there are no initial conditions, the capacitor acts as an open circuit and the inductor acts as a short circuit.

Suppose we want to design a synchronous circuit that processes a string of 0’s and 1’s. Given a string, it produces another string by replacing the first 1 in any subsequence of consecutive 1’s by a 0. Consider the following example. Input sequence: 00100011000011100 Output sequence: 00000001000001100 A Mealy Machine is a state machine where both the next state and the output are functions of the present state and the current input. The above mentioned circuit can be designed as a two-state Mealy machine. The states in the Mealy machine can be represented using Boolean values 0 and 1. We denote the current state, the next state, the next incoming bit, and the output bit of the Mealy machine by the variables s, t, b and y respectively. Assume the initial state of the Mealy machine is 0. What are the Boolean expressions corresponding to t and y in terms of s and b ?
Three friends A, B and C worked together to complete the work. A takes 4 days more to complete same work done by A and B. Work done by C in 4 days is equal to the work done by A in one day. Work done by B in 3 days is equal to the work done by C in 8 days. Find the time in which work will be completed if all three worked together.
