You are given an input signal with a maximum input frequency of 1 kHz. Also, given that the Nyquist criteria of a minimum sampling frequency is two times the highest input frequency, are there any potential problems of sampling the input signal at a sampling rate of exactly 2 kHz? What if there is no antialiasing input filter and the input signal exceeds the Nyquist sampling frequency criteria to a value of 0.6 times fs ? What affect would this have on the output?

Solution: the categorization of functional and non-functional requirement are as follows: some of the more typical functional requirements include: • business rules• transaction corrections, adjustments and cancellations• administrative functions• authentication• authorization levels• audit tracking• external interfaces• certification requirements• reporting requirements• historical data• legal or regulatory requirementswhile,some typical non-functional requirements are: • performance – for example response time, throughput, utilization, static volumetric• scalability• capacity• availability• reliability• recoverability• maintainability• serviceability• security• regulatory• manageability• environmental• data integrity• usability• interoperability
