What does LPC mean in TELECOM
Linear Predictive Coding (LPC) is a signal processing technique used in speech synthesis and recognition. It is based on the linear predictive model of speech production, which models the human vocal tract as an all-pole filter. The technique was first proposed in the 1960s and has since been widely used for speech coding applications such as voice over IP (VoIP) and mobile telecommunications.

Essential Questions and Answers on Linear Predictive Coding in "COMPUTING»TELECOM"
What is Linear Predictive Coding?
Linear Predictive Coding (LPC) is a signal processing technique used in speech synthesis and recognition, based on the linear predictive model of speech production.
How does LPC work?
LPC works by modeling the human vocal tract as an all-pole filter, where each pole corresponds to a separate frequency band of the input signal. The output of the filter can then be compared to the original signal to determine how much energy is present in each frequency band.
What are some applications for LPC?
LPC has been widely used for speech coding applications such as voice over IP (VoIP) and mobile telecommunications. It can also be used for audio compression and other digital audio applications.
Are there any disadvantages to using LPC?
One disadvantage of LPC is that it requires more computational power than other methods because each pole must be individually determined from the input signal. This can make it difficult to use real-time applications where reduced latency is important. Additionally, poor quality recordings can lead to distorted output signals which may degrade performance further.
How accurate is LPC compared to other techniques?
In general, LPC allows for extremely accurate representations of input signals due to its ability to accurately capture many details within a given frequency range. For example, when applied to voice signals, research has shown that it outperforms alternative methods such as adaptive differential pulse code modulation (ADPCM).
Final Words:
Linear Predictive Coding (LPC) is a powerful signal processing technique that has been widely used in many areas ranging from mobile telecommunications to audio compression. Although it requires higher computing power than some alternative methods, its ability to accurately capture detailed information from within a given frequency range makes it well-suited for many tasks involving speech or audio signals.
