A state diagram of a logic gate which exhibits delay in the output is shown in the figure, where X is the don’t care condition and Q is the output representing the state



The logic gate represented by the state diagram is

An operational-amplifier circuit is shown in the figure.



The output of the circuit for a given input v₁ is

In 8085A microprocessor, the operation performed by the instruction LHLD 2100${}_H$ is

A non-ideal voltage source V${}_S$ has an internal impedance of Z${}_S$ If a purely resistive load is to be chosen that maximizes the power transferred to the load, its value must be

The torque-speed characteristics of motor (T${}_M$) and load (T${}_L$) for two cases are shown in the figure (a) and (b). The load torque is equal to motor torque at points P, Q, R and S



The stable operating points are
