Show the algebraic expressions for all carries of the 4-bit ADDER (C1, C2, C3, C4) in terms of CG and CP. Show the schematic for the 2-LEVEL implementation of the CARRY GENERATOR of the CARRY-LOOKAHEAD adder using NAND gates with any number of inputs. The circuit has the following inputs and outputs: inputs C0, CGi, CPi, where i= 0, 1, 2, 3, outputs: C1, C2, C3, C4.

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
