higher and reliable operation is required. Since‚ the operation is automatic error due to manual operation will be prevented. Once the arrival of the train is sensed‚ the sensed signal is sent to the microcontroller via‚ wired or wireless transmission and it checks for possible presence of vehicle between the gates. Subsequently‚ buzzer indication and light signals on either side are provided to the road users indicating the closure of gates. Once‚ no vehicle is sensed in between the gate the

CS601: Computer Networks lab EXERCISE - 1 Write a Program in C/ C++ for error detecting code using CRC-CCITT (16 bit) Objective: To enable the receiver of a message transmitted through noisy channel to check whether the message has been corrupted. The aim of an error detection technique is to enable the receiver of a message transmitted through noisy channel to determine whether the message has been corrupted. To do this‚ the transmitter constructs a value called a checksum that is the function

interest in convenient communication has heightened the need for digital communication development. This report would introduce an ambulance service system. As an emergency system‚ it should be quick response; in addition‚ the quality of the signal transmission is also very important. Then it is necessary to choose the appropriate components. Graph 1 [1] 1. Digital source Generally speaking‚ the graph shows above is a general block diagram of a digital communication system

Circuit/Packet | Packet | The existing 3G W-CDMA standard will be replaced in 4G by VSF-OFCDM and VSF-CDMA. VSF-OFCDM allows extremely high downlink connections‚ both indoors and outdoors. VSF-CDMA provides high-efficiency‚ high-speed packet transmissions for the uplink. The 4G adoption of concatenated FEC (Forward Error Correction) will allow much larger data packets to be transmitted and at the same time reduce the bit error rate. This will increase the overall data through-put. One of the

1 What are two reasons for physical layer protocols to use frame encoding techniques? (Choose two.) to identify where the frame starts and ends* to distinguish data bits from control bits* to reduce the number of collisions on the media to increase the media throughput to provide better media error correction 2 Which statement is correct about multimode fiber? Multimode fiber commonly uses a laser as a light source. Multimode fiber cables carry signals from multiple connected sending

This specifically means that digital communication is data communication of information that is converted from text to code digitally. Digital communication can also be effective communication dealing with web‚ multimedia‚ video or graphics‚ and digital media. Some forms
