Question 1: Assume you are required to design a logic circuit enclosed in a black box to detect a password, which can be changed by an authorized administrator any time. The password is composed
of a squence of a 4-bit decimal number, i. e., each bit is in the range 'O' to '9' and sent in BCD format.
As stated above, the password should be suitable to change any time, i. e., while the initial password
can be "0120", it can also be replaced by "3456" any time by the administrator. In this design, you are
allowed to use only 4-bit parallel output shift-registers with a single-serial input data line and 4-bit
magnitude comparators. The password to detect is "1234".

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.
