Hi there,
I'm not an PCB layout expert. This is my third time using
Orcad PCB Editor 15.5. Previous occasions things were setup for me, such as the layers, sheet size, etc.
With that said, I'm having problems generating Artwork for my 1 layer board. The top etch layer is not coming out...
antenna beams
Since I'm around, the quick anwer with ref is yes,
Definitely yes!
Just google something like 'two beam antenna array'
and you find info.
There is also a CD with the book, but it's not much value.
It contains colour layout figures from the book.
Dan actually works near where I live. Cool guy.
Re: Puzzle: Distinguising equivalent circuits inside black b
wow cool!
steer:
did you actually get that yourself or have you encounter this question/answer
before?

Re: Puzzle: Distinguising equivalent circuits inside black b
Sorry I made a mistake IanP,
In box2:
The ideal constant current source outputs 1 amp (not 1V), so if you
short the terminals outside the box, 1 amp will flow through that short
circuit.
However if you did this to the first...
Can someone tell if it is possible to distinguising the following two
black boxes:
Box 1 - From the interfacing box's terminnal a
1V ideal voltage source with a 1Ohm Resistor in series is connected.
Box 2 - From the interfacing box's terminal a 1V ideal current souce with a
parallel...
QAM Spreading due to LPF
Hi
I am modulating OFDM symbols,
sending it out to filters,
performing low pass filtering with proper BW specs. ,
then sampling and demodulating the signal by taking the FFT
the plotting the QAM symbols on the constellation.
--no channels are involved.

Re: Finding SNR
tohji: sometimes you want to clip your signal if you have a very high
peak-to-average power ratio. This way you tradeoff clipping for
better usage of the ADC range for most part of your signal.
flatulent: thnx for the troubles. the paper has what i'm...
Finding SNR
Hello,
This equation is for an ADC:
SNR = 6.02n + 1.76 dB , where n is the number of bits
However, this equation has a few assumptions and is invalid
if your input clips and saturates the ADC.
Assuming my input signal does clip and has a guassian distribution,
what is the...
TI - 6711 pinout
Hello,
On the DSK6711 from 'TI' i am confused about where to find
CLKS on the external J2 connector. Where is this pin? Does it
share a pinout with one of the serial ports?
Sparrow
thnx for the responses, it was nice to share ideas on this.
the cpld is a -Al ter a- Flex10K.
-- one signal does not reach 3Vpp to the scope, that is why I wanted to
level shift before feeding.
I shall try to use a buffer to compensate from TI.

What device do I need to help interface 3.3V digital output
to 5V input on CPLD???
I just have 3 signals to interface, with max freq of operation at 75MHz.
I would like to be able to buy the component from Digi Key.
