Hi peacherwu,
The step 2 deepends on what kind of codec you want to implement, encoder or decoder, and what kind of algorithm you use, how many mutiplicer or adder, how you can optimze your algorithm, what is your implement structure and how you can optimize your algorithm, do you need implement...
Re: convolution
Convolution only when you related to the LTI system, you can get fully undersdanding.
The result of convolution is the system h(n) response to the input x(n).
The mathmatic is quit abstract for we engineer guys..:-)
I am not quite understand your situation, if your received signal is a DSB signal, you can apply a bandpass filter to get a SSB signal.
For the second, you can either use a Hilbert Transform to get a anylitical signal, I, Q, apply each path with your complex FIR filter.
Hi All,
I have a baseband signal 0Hz~48KHz, and sampling rate is Fs = 1.536MHz, I need to mix this base signal to IF, which is about 384KHz, but when doing mix, I do not want the Double-Side-Band (DSB) signal but Single-Band-Signal (SSB), so I will considering design a Hilbert transform to mix...
calculate the inverse of a fir filter in matlab
For your information, for the response of filter, I do respectly a bit disagree with you while by using inverse DFT instead of DTFT, for the former is disceret frequency response while the latter is the correct continuous period discrete time...
convert fixed point to hex
I think you need to konw what algorithm you want, either Fix-Point alogrithm or floating-point alogrithm, for fix-point, the above explaination is sufficient, but for floating-point, you need to convert the hex-reprensentation of your floating numbers, and again you...
interview questions on digital signal processing
Why are we using windows when doing FFT?
Why are we using overlap when doing FFT?
What is the trade-off of selecting a window to do FFT?
What is the relationship between phase noise in Frequency and jitter in time domain?
What is the concern...
Hei Guys,
I have a problem about IIC slave, as I know, each of the slave has it's address, master send address and slave response data to master..
But when I have a EEPROM, address space is 0x00~0x1K, and a LCD with address space 0x00~0xFF,
I want to kwnow how to distinguish between the 2...
Hei guys,
Step(1) I was using modelsim to generator result.fsdb file for Debussy first,
Step(2) then I load DUT and Bench into debussy design file,
Both Setp1 and Setp2 done well, but when I load waveform file result.fsdb,
it turns wronng and I can not seen any waveform.
Could you guys...
Re: Xilinx Post-Sim Help
I have solve the problem, it's because the recover of reset before clk posedge time does not match the SDF(standard delay file), modify the reset stimus, it works ok now.
Anyway, thans you guys care.
Regards,
Chris
x_lut4mux16
Hi guys,
when I do post-sim for Xilinx device on Modelsim, although I have compile all
the libs, but it reported that "Instantiation of 'X_LUT4MUX16' failed. The design unit was not found", and I have check all the simulation lib of "

hi, when I run post simulation on Modelsim, it report the erro infor about this, can you guys help me?

(cordic)(timing)
Hi guys,
I have a problem when implement the CORDIC, I use CORDIC to geneartor triangle value from [0, pi/2] in DDS design and I use parallel strucuture and
therefore, there is a very big delay because of CORDIC iterative.
However, we must have run the DDS at 100MHz, as...
dds met phase dithering
thanks, Frank.
Yes, you r right, need to add dither before trunction, but i still can not figure out how to find the correct model for the dither..
