Lab 6 (Classless Subnetting)

Given that the base address is FoH. 1. Create a new asm project “Lab2_Q1.asm". Assume that port A of 8255A PPI is connected to 8085. Write assembly code to send the value of FFH to FoH. Enter a delay of 2 ms for each transmission.

The following data are transmitted in a serial communication system (P is the parity bit). What parity is being used in each case? a. ABCDEFGHP = 010000101 b. ABCDEFGHP = 011000101 c. ABCDP = 01101 d. ABCDEP = 101011 e. ABCDEP = 111011

6. Calculate the check bits (find the codeword) for the bit-pattern (100101011), usingHamming code error correction method.

5. Write an assembly program that calculates the mean of the following array. (5) *Please write code comments* AREA myData, DATA, READWRITE array DCD 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16,

State a bit rate and maximum number of channels in T-1 and T-3 telephone TDM system.

(c) Write a VHDL code to implement the above counter using conditional statement "case". You need not necessarily use a synchronous load mechanism.

WR* = 1 for an I/O read bus operation.  True  False

Explain why NRZ coding is not attractive for signal transmission applications?! Short answer please

* You have been asked to create a subnet that supports 16 hosts. What subnet mask ?should you use .255.255.255.252 • 255.255.255.224 .255.255.255.240 • 255.255.255.248 * ?How does a switch differ from a hub • A switch does not induce any latency into the frame transfer time. • A switch decreases the number of broadcast domains. • A switch operates at a lower, more efficient layer of the OSI model. . switch tracks MAC addresses of directly- connected devices. Which OSI layer header contains the address of a destination host that is on ?another network • Network

please answer with solution Determine the “M” value and number of data bits that can be represented by a single symbol using PSK where the possible phase values per symbol can be {π/4, 3π/4, 5π/4, 7π/4}. a. M=2, N=1 bit per symbol b. M=4, N=2 bit per symbol c. M=6, N=3 bit per symbol d. M=8, N=3 bit per symbol

In a TDMA system, the number of overhead bits and the number of total bits are 332 bits and 1250 bits. What will be the efficiency of the system?

Please can you provide me with the full solution for this question

Answer in text format only!!

A code 1011 need to be send to the receiver. Using, Hamming code find out the code-word and the mechanism to check the corrected data. (Assumptions: Right to Left with Even Parity)

Q.3) You want to transmit the message &$ a. Encode this textual message into a sequence of bits, using 6-bit ASCII coding, followed by a seventh bit for error detection, per character. The seventh bit is chosen so that the total sum of bits using XNOR gate is zero How many total bits are there in the message? b. Assuming the bit duration 10 ms, plot the Dicode RZ line code. c. Assuming the bit duration = 10 ms, plot the Bi--M code. d. Assuming the bit duration 10 ms, plot the Miller line code.
