Let the discrete-time signal be defined by z[n] be defined by (additional value

Let the discrete-time signal be defined by z[n] be defined by (additional values are zero) n a. Express z[n] as a sum of step functions. b. Is z[n] an energy signal, a power signal or neither? If z[n] is an energy signal, compute its energy. If z[n] is a power signal, compute its power. If z[n] is neither, explain why. c. Is z[−n+7] causal? 2. Let the discrete-time signal z[n] be shown below. a. Express z[n] as a sum of step functions u[n]. b. Sketch y[n]=∑m=−11(m+1)z[n−3m]. Remember to label your axes. c. Is z[n] an energy signal, a power signal or neither? If z[n] is an energy signal, compute its energy. If z[n] is a power signal, compute its power. If z[n] is neither, explain why.

 Memory is the portion of a computer or other system that stores binary  data. In a computer, memory is accessed millions of times per second, so  the requirement for speed and accuracy is paramount. Very fast  semiconductor memory is available today in modules with several GB (a  gigabyte is one billion bytes) of capacity.  
 
answer the following:
Question 1 – Explain what a ROM is and how it works.
Question 2 – Discuss special types of memories such as FIFO and LIFO.
