1, The full form of PLC is Programmable Logic Controller. It’s used on Computing ,Hardware in Worldwide

A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures.

A programmable logic controller (PLC) or programmable controller is an industrial digital computer which has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, or robotic devices, or any activity that requires high reliability, ease of programming and process fault diagnosis.

PLCs can range from small modular devices with tens of inputs and outputs (I/O), in a housing integral with the processor, to large rack-mounted modular devices with a count of thousands of I/O, and which are often networked to other PLC and SCADA systems.

They can be designed for many arrangements of digital and analog I/O, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory.

PLCs were first developed in the automobile manufacturing industry to provide flexible, rugged and easily programmable controllers to replace hard-wired relay logic systems. Since then, they have been widely adopted as high-reliability automation controllers suitable for harsh environments.

A PLC is an example of a “hard” real-time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result.

8, The full form of PLC is Packet Lost Concealment

Packet loss concealment (PLC) is a technique to mask the effects of packet loss in voice over IP (VoIP) communications. When the voice signal is sent as VoIP packets on an IP network, the packets may (and likely will) travel different routes. A packet therefore might arrive very late, might be corrupted, or simply might not arrive at all. One example case of the last situation could be, when a packet is rejected by a server which has a full buffer and cannot accept any more data. Other cases include network congestion resulting in significant delay. In a VoIP connection, error-control techniques such as automatic repeat request (ARQ) are not feasible and the receiver should be able to cope with packet loss. Packet loss concealment is the inclusion in a design of methodologies for accounting for and compensating for the loss of voice packets.

Packet loss is a major source of voice distortion in VoIP (Voice over IP). Packet loss may be due to several reasons: routing problems, transmission errors, and network congestion in VoIP communications. To mitigate the effect of these losses on voice quality, PLC (Packet Loss Concealment) mechanisms are introduced in the decoders to reconstruct the lost frames. Many decoders have PLC algorithms as G729.A and G723.1. This decoders generally have bad correcting losses when there are many consecutive lost packets. For reinforce the PLC algorithm performance of decoders, several PLC techniques used both at the receiver level such as PLC technique based on ITU-T G711 Appendix I, then is longer used in VoIP. In this paper, we proposed the method of polynomial interpolation integrate at PLC technique based on ITU-T G711 Appendix I, for finding the synthetic signal approximation as an original signal by interpolating samples of pitch. Evaluation results of subjective PESQ confirmed that method proposed can effectively evaluate the speech quality in the IP environment.
