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.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

At 12 noon, the count in a bacteria culture was 400; at 4: 00 pm the count was 1200 let p(t) denote the bacteria cou population growth law. find: (a) an expression for the bacteria count at any time t (b) the bacteria count at 10 am. (c) the time required for the bacteria count to reach 1800.
