Performance Analysis of Upsample Filter for Sample Rate Converter
Manish Sabraj · Signal & Image Processing An International Journal · 2012
Now a days many signal processing tasks are performed in the digital domain. Various sample rates are used on the basis of required signal quality and the available bandwidth. Sample-rate conversion is therefore inevitable to interface systems with different sample rates. The aim of digital sample rate conversion is to bring a digital audio signal from one sample frequency to another. Some information is lost while sampling.The distortion of the audio signal introduced by the sample rate converter should be as low as possible. The generation of the output samples from the input samples may be performed by the application of various techniques, In this paper, a new technique of digital sample-rate converter is proposed. We discuss performance analysis of upsample filter in proposed digital sample rate converter.
