An ideal OPAMP is used to realize a difference amplifier circuit given below having a gain of 10. If x = 0.025, the CMRR of the circuit in dB is _______.

In the circuit given below, the opamp is ideal. The input vₓ is a sinusoid. To ensure v${}_y$ = vₓ, the value of C${}_N$ in picofarad is _____.

In the circuit given below, the OPAMP is ideal. The value of current I${}_L$ in microampere is ______.

A 4 to 1 multiplexer to realize a Boolean function F (X, Y, Z) is shown in the figure below. The inputs Y and Z are connected to the selectors of the MUX (Y is more significant). The canonical sum-of-product expression for F (X, Y, Z) is

A synchronous counter using two J – K flip flops that goes through the sequence of states: Q₁ Q₂ = 00 → 10 → 01 → 11 → 00 …. is required. To achieve this, the inputs to the flip flops are
