Direct Form II The signal flow graph for the Direct-Form-II (DF-II) realization of the second-order IIR filter section is shown in Fig.9.2. Figure 9.2: Direct-Form-II implementation of a 2nd-order digital filter.The difference equation for the second-order DF-II structure can be written...
Digital Signal Processing (DSP) is the manipulation of real-world signals within a digital computer, using mathematical techniques to enhance, change, or display the data in a specific way. It involves converting analog signals (such as audio or video) into digital form and performing various ope...
Meanwhile, Martucci [23] proposed a new formulation for these DTTs, denoted by convolution form. In this formulation, the orthogonality property of the kernel matrices was waived for most DTT types. Such formulation was shown to be more appropriate for applying the convolution-multiplication property...
Antares Audio Technologies, the software DSP innovator that brought the world the Auto-Tune, has come forth with their latest digital mojo-in-a-box called the Microphone Modeler ($249). Perhaps you've heard of this new plug-in that claims to be able to take recorded input from even the ...
A DDS chip, or direct digital synthesizer, produces an analog waveform—usually a sine wave, but triangular and square waves are inherent—by generating a time-varying signal in digital form and then performing a digital-to-analog (D/A) conversion. DDS devices are primarily digital, so they ...
DSP and FFT-based approaches provide a wealth of test and measurement capabilities and form the core of spectrum analyzers, which, in turn, are a key component of external testing. For SOC implementations, incorporation of an FFT can be costly in terms of area, particularly for high-resolution...
To include a specific description about the digital signal processor (DSP) interface, use the description command in DSP farm interface configuration mode. To disable this feature, use the no form of this command. description string no description string Syntax Description string Character string...

Due to the value of F in this example, 2 or 3 timer periods are needed to change the value of I. Therefore, the preservation of the form of Vi(t) is not guaranteed from one period of the synthesized signal to another. In particular, with the DDS there is no need for a fixed and...
The baseband processor receives the digitized signal in the form of complex-valued samples from the A/D and delivers the decoded bit stream to a higher layer protocol and application processor. It first removes the cyclic prefix, transforms the signal into frequency-domain by an FFT operation, ...
