If only problem is that you shoud use ADC08100, which can't work properly with sampling rates below 20MSPS you shoud use only a some 8 bit latch. You shoud simply write on latches every second, fifth, 10th etc sample. You just need to generate proper strobe signal, which will drive Enable pin of...
Digital scope comparison
I wondering wich DSO is better - TDS 2022 or Agilent 3202A. I have some expirience with tektronix DSO, but never work with digital Agilent scope. What is your impression about them? TDS2012 is very nice, simple in use, very compact, and have very high sample rate -...
Re: ribbon cable problem
I think it can't. In some cases, short distances, single signal( i.e. one pair of wires) no too high frequency may be it works. But my answer is Not. Current practical designs proove this, as far as I know.
As far as I know difrencies are small - less than 1 meter. In most practical casses you don't calibrate your device exactly on sea level. In adition there is a waves :-). I live very close to the sea, terein is even but actual elevation of my home and my workdesk respectevly is about 3-4 meters...
Wow! Some transistors could do the job if they are properly connected. ;-)
It is no so simple task in my opinion. Probably the easiest way is to use some buffer OP amp from Maxim( former Elantec products)or AD. Actualy AD8010 is a good choice. It is very siple fir connection but in any case...
Another issue that you must keep in mind, is that water boils at lower tepmeratures with rise of elevation above sea level. For example at 500 m above sea level, water boils at the 96.7 degree celsius.
Re: waveguide..?
It is simple. You need just some pipe wich internal surface is covered with some conducting material. In general waveguides a manifactured from brass, covered with very high quality layer of silver. Geometric dimensions determine frequency range of wavegude, propagated modes...
fast transient burst filter
With digital spectrum analyser. probably :). But in transcients are wide bandwith in general You can't use some notch filter to suppres them.
I think that you shoud first reexamine grounding, coupling and isolation of your digital circuit. With proper design...
Re: Pulse Ampfier
You cannot use "simple CE transistor" because you can not find transistor that has reqired gain at this conditions - 10A and 10MHz. In most casses there is sharp gain decreese in region above several amps, severam megahertz.
In fact it is not simple task, as you can think...
there is no "digital" or "sine" frequency. There is signal frequency and data rate speed. For example You can supply DAC with 10 milion bytes per second and have signal frequency form DC to 5 MHz. 5Mhz is maximum because of the Nyquist rule. Look at th picture: Signal frequency is 7.81MHz and...
Re: Phase margin
It is tradeof between stability and gain. To avoid oscilations in feedback amplifier, phase must be less that 180 at unity gain frequency. You can make frequency compensation with less phase margin, to obtain bigger gain at lower frequency, but you risk to make oscilator, not...
**broken link removed**
In fact there is quite fast transistors in labs. On the other hand, there is a way to design amplifier, wich have frequency band higher than transistor's transit frequency.
So 70GHz amplifier is not the limit!
