Requirement Analysis

A process that determines the user expectations for a software product is called requirement analysis. In software engineering, requirement analysis is known as requirement engineering. It involves communication with end-users and stakeholders to determine whether the system or software requirements are validated, conflicts are solved, and key requirements are documented. The first activity of the Software Development Life Cycle (SDLC) is requirement analysis.

b) Draw the state diagram of the machine that performs the following operation: The machine turns on with output at '0' thanks to asynchronous clear. At each clock trigger, the machine reads the input X. If the input is read at '0' for three times in a row, the output becomes '1', and it does not return to the initial state until three '1' are read in a row.
Suppose we wish to design a car security system that operates as follows: • There are only two states: "siren off" and "siren on" • There is one combinational output: 0 - lights not flashing or 1 - lights flashing. • There are three combinational inputs: M(master), D(door), and V(vibration). Use the names M, D, and V for these inputs in the given order MDV. • M: 0 - off, 1 - on • D: 0 - door closed, 1 - door opened • V:0 - no vibration detected, 1 - vibration detected The circuit works as follows: • If the siren is currently off, it is turned on and the lights flash when the master is on and either the door is opened or vibration is detected. (This is a regular or, not an exclusive or). • If the siren is currently off, it will remain off and the lights will not flash when either the master remains off or if the master is on but neither the door is open not vibration is detected. • If the siren is currently on, it will remain on and the lights will flash as long as the master is on. •…
