Consider the circuit shown. The input VI = 10sin2π106t. Calculate the duty cycle of the output.

Consider the circuit shown. The input VI = 10sin2π106t. Calculate the duty cycle of the output. Correct Answer 0.36

Duty cycle for a signal = Duration when output is VSat/Total period Let input = VI = 10 sinθ The output goes to +VSat whenever the input VI crosses amplitude of 4V. Thus 4 = 10sinθ Θ = sin-1 0.4 = 0.411 rad = 23.57° The duty cycle = /360 = 180-47.14/360 = 0.36.

In the question one statement is given, followed by two conclusions, I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statement. Statement: A function is a relation between a set of input elements and a set of possible output elements where each input is related to exactly one output. Conclusion I: Every input element is related to every output element. Conclusion II: Every input element is related to one element of the output.

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 ?
