AN-929 Microcontroller Interface to the ADC12038 Families (Rev. C)
Texas InstrumentsThe ADC12038 families are 12-bit plus sign sampling ADC converters with serial I/O. These devices haveconfigurable analog multiplexers with 2 4 or 8 input channels. On request these A/Ds perform a selfcalibration routine that minimizes linearity zero and full-scale errors. To minimize power consumptionthese devices have a power down mode that can be accessed by hardware (PD pin) or by a
Fast Fourier Transform Algorithms of Real-Valued Sequences w/the TMS320 Platform
Texas InstrumentsThe Fast Fourier Transform (FFT) is an efficient computation of the Discrete Fourier Transform (DFT) and one of the most important tools used in digital signal processing applications. Because of its well-structured form the FFT is a benchmark in assessing digital signal processor (DSP) performance. The development of FFT algorithms has assumed an input sequence consisting of complex numbers.
