Rational Sampling Rate Converter using Coefficient

In this paper, we proposes an efficient structure for rational sampling rate converter. Finite impulse response filter is used in between upsampler and downsampler in order to avoid image spectra and aliasing effects respectively. Coefficient symmetry of the linear phase filter is used so that number of required multiplication per output sample is reduced.

Rational Sampling Rate Converter Design Analysis using Symmetric Technique

In this paper we proposed an efficient structure for sampling rate conversion by rational factor of L/M, where L is upsampling factor and M is downsampling factor. In this method, the coefficient symmetry of the linear phase filter is used. In this way, the number of required multiplications per output sample is reduced. For implementation we use linear phase FIR filter. The symmetric FIR filte...

Conversion between Arbitrary Sampling Rates: an Implementation Cost Trade-off Study for the Family of Farrow Structures

We investigate and compare the computational loads of different implementations of a system for asynchronous sample rate reduction: The cascade of a preceding synchronous polyphase L-Interpolator, an asynchronous sample rate converter applying five different Farrow structures being based on Lagrange interpolation and a successive synchronous polyphase M-decimator. For a limited range of require...

Design of digital systems for arbitrary sampling rate conversion

The conversion of digital signals from a given sampling rate to a second, arbitrary sampling rate, with both sampling rates derived from independent clock generators, is revisited. A general approach to arbitrary sampling rate conversion is presented from which two efficient realisations are deduced. The computational expenditure of both realisations is derived under the restriction of finite c...

Reconfigurable optical quadrature amplitude modulation converter/encoder using a tunable complex coefficient optical tapped delay line.

We experimentally demonstrate a reconfigurable optical converter/encoder for quadrature amplitude modulated (QAM) signals. The system utilizes nonlinear wavelength multicasting, conversion-dispersion delays, and simultaneous nonlinear multiplexing and sampling. We show baud rate tunability (31 and 20 Gbaud) and reconfigurable conversions from lower-order QAM signals to higher-order QAM signals ...
