b) PC1 is assigned the IP address 192.168.13.8 with a subnet mask of 255.255.255.224. PC1 sends a packet to PC2 which has an IP address of 192.168.13.65. Is PC1 (192.168.13.8) and PC2 (192.168.13.65) in the same subnet based on the subnet mask of PC1 (255.255.255.224)?

Instructions:

1. Solve the following problems in a MATLAB script. You will be allowed to submit only one script, please work all the problems in the same script (Hint: careful with variables names)

2. Show your work and make comments in the same script (Use %). Please write your name in the first line of the scrip with %

3. It is OK to work with other students, but what you submit should be your own work – not something copied from someone else.

How does a diode affect an AC signal?

The magnetic flux density in a region of free space is given by B = −x² ax + 2y³ ay − 2z az T. Find the total force on the rectangular loop shown which lies in the plane y = 0 and is bounded by x = 1, x = 3, Z= 2, and Z= 5, all dimensions in cm. The current is 30 ampere in anticlockwise direction.

Design a microcomputer system using a uP 8086 10 Mhz. This system must have a Coprocessor 8087, a parallel connector, a serial connector, ADC and DAC connector for data conversion, a 16 byte seven segment display, a 64-key matrix keyboard, a USB connector thru a DMA for high speed data transfer. A special connector to connect a printer. The system must have an interrupt controller to handle all the I/O interface. The main memory size will be 1 Mbyte.

Show all the diagrams needed to construct your design including all the I/O interface and devices connected, show a memory map and the type of memory you will need for you design including the configuration and decoding system. You must include the programming needed for set up the complete system. Use pseudo code for each driver and program each of the interface needed.
