Decimator Volume 1 album launch on December 11, 2018.
Music recording powerhouse Decimal Records is set to release its first compilation album, '
Decimator Vol 1'.
The square
decimator [[*].sup.2] block [5] is used to calculate the signal energy [E.sub.y] in Equation (17) and [E.sub.z] in Equation (18) from the error signals [e.sub.y] and [e.sub.z] and then put into the SDA blocks.
The first filter is a 4th order low pass Cascaded Integrated-Comb (CIC)
decimator filter with a decimation factor of 16.
This type of filter consists of 3 stages: the integrating stage, the
decimator or integrator stage, and the comb section.
The DS or
decimator discards (Z -1) number of samples and keeps the remaining samples.

decimator", IEEE Trans.

decimator with improved magnitude response," in Proceedings of the 14th IEEE International Conference on Electronics, Circuits and Systems (ICECS '07), pp.
The digital data is received at a sampling clock of 50 MHz and then processed as follows:16 bit high speed ADC Data is passed through a digital Mixer consisting of a 50 MHz Numerically Controlled Oscillator (NCO), a multiplier (16x16 bit), suitable low pass decimation and compensating filters (CIC and CFIR filters) of bandwidth 5 MHz to filter the entire unwanted signal outside the band and a 10 rate
decimator to bring down the sampling rate to 5 MS/s for further processing Finally the DDC output will be In phase (I) and Quadrature (Q) signals.
The five subcircuits are reviewed as (i) an input
decimator circuit, (ii) an 8-point AI-encoded 1D DCT block for column-wise computation, (iii) an AI-based transposition buffer, (iv) four parallel instantiations of the 8point AI-encoded 1D DCT block for row-wise computation, and (v) the FRS circuit for decoding AI-encoded 2D DCT coefficients.
