PDF-High performance IIR filters for interpolation and decimation

1 for interpolation and decimation Dr David Wheeler Technical Director EnSilica July 2013 Abstract This technical note looks at implementing high performance polyphase IIR filters with very. Linear and Spline Interpolation The 64257rst function that we will look at is interp1m Speci64257cally we look at interpolation that 64257ts a local polynomial to the data in a small window to 64257ll in the extra information The synopsis of this f DAC5688 Input FIFO /Demux Complex Mixer Quadrature Modulator DAC CLK & PLL Interpolation Mixer & NCO QMC Inverse SINC Filter ADS62Pxx Onufriev. Over-all: Very good idea to use more than one source. Good motivation (use of graphics). Good use of simplified, loosely defined -- but intuitive -- terms (e.g. "undisturbed"). Very good use of illustrative graphics for introduction of new concepts. Obviously, took quit a bit of effort to prepare the talk. This very serious effort offsets some of the drawbacks, see below..

A Sampled or discrete time signal x[n] is just an ordered sequence of values corresponding to the index n that embodies the time history of the signal. A discrete signal is represented by a sequence of values x[n] ={1,2,. Zhu, Eric L. Turner, Christian R. Berger, Larry . Pileggi. , Franz . Franchetti. September 22, 2011.
