A Design of HDB3 CODEC Based on FPGA


ABSTRACT
The basic principles and structure of HDB3 was briefly introduced in this paper, and the shortcomings of the existing HDB3 encoder and decoder was analyzed. Then a new design of HDB3 encoder and decoder based on FPGA was proposed, and the hardware design circuit and software simulation were introduced. The simulation was achieved through the VERILOG-HDL in EP2C35F672C8 chip of CycloneII series in the d ....etc

Development of an Interest Calculation system for a retail bank

Consider a retail bank which collects money from customers and in return gives them an interest at pre determined rate. Our objective is to automate this process of interest calculation. The system developed should calculate interest daily for each account having balance more than zero at the correct interest rate. This interest calculated will be cumulatively stored in a table which will be ....etc

HEATSINK CALCULATION AND EXAMPLES
In many cases, GS-Rx and GSxTy-z modules don’t require any additional cooling methods because the dimensions and the shape of the metal boxes were studied to offer the minimum possible thermal resistance case to ambient for a given module. It should be remembered, that GS-R and GS-T modules are power devices i.e. products that deliver power and dissipate power and, depending on ambient temperature, an additional heat-sink or forced ventilation or both may be required to ....etc

Air brakes are used in commercial vehicles, which require a heavier braking effort than that can be applied by the driverâ„¢s foot. The following layout shows the arrangement of the air braking systems in heavy vehicles.Compressed air from compressor passes through the unloader valve and maintains its pressure. This air is stored in the reservoir. From the reservoir it goes to the Brake Chambers through many brake valves. In the brake chamber this pneumatic force is converted into the mechanical force and then it is converted into the rotat ....etc

SYSTEM DESIGN & DEVOLOPEMENT IN CALCULATION OF RESPONSE TIME FOR AIR BRAKE SYSTEM
INTRODUCTION
COMPONENTS OF AN AIR BRAKE SYSTEM:
Air brake system consists of the following components:
Compressor:
The compressor generates the compressed air for the whole system.
Reservoir:
The compressed air from the compressor is stored in the reservoir.
Unloader Valve:
This maintains pressure in the reservoir at 8bar.When the pressure goes above 8 bar it immediately releases the pressurized air to bring the system to 8-bar press ....etc

lcm calculation method



LCM


LCM stands for least common multiple.

LCM of two numbers is the smallest number that is a multiple of both the given numbers.

Example

What is the LCM of 4 and 6?
Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76
Multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Common multiples of 4 and 6 are simply the numbers that are in both lists: 12, 24, 36, 48, 60, 72, ....
So the least common ....etc

Hi am ElMehdi, I would like to get details on simulink hdb3 .. I think that this is not available by default in the simulink tool, I need to do a simulation of a transmission chain that uses a digital entery coded in HDB3 as an information to modulate it and transmit it after that. ....etc
