Hi,
I suggest you reference very old IBM PCXT's technical manual.
Inside the manual, you can find the detail circuit of the floppy disk interface. You can reference it to build it for your own system.
Also, the bios source list also can help you to program your own interface.
Hi wstorts,
I donot suggest you to build 1024 channels switches. it need multi-stage of switches and it will cause a big distortion of the signal. The distortion will accumulate to the last stage and make the output signal very noisy.
1024 coaxial cables will bring you big problem in the cable...
Hi,
I have this book which may satisfy your need. I have read it and I feel it is very good on both theorically and engineering.

Hi Lewish,
Yes, it is a very easy, so it is common, trick. If I face your situration, I'll write a simple program to re-arrange the data and not going to hardware.
All the computer can make it very soon to verifly the result.
This is my style for your reference.

Hi Paul51,
The phase margin is not very meaningful in the real world. The problem we found about the phase margin is the phase linearity or phase margin Vs frequency.
If you want to measure the phase error or insertion phase, a vector network analyzer will help.
The other terms named...
Hi Paul51,
I don't think it is guilty to study on other people's work. We can learn from other people under the respect of the original. The similar case happened on the IBM PC bios. Finally, the reverse engineering is legal.
Regarding to your question, the program you need is the...
Hi,
I just read a document and memtioned there is a waterproof standard called IP65.
Does anyone can provide some web pages which descript it.
Thanks and Regards,

Jbartos is talking about the directly damage from lighting. We need to consider this issue as basic consideration.
After you have protect from the direct damage from lighting, you need to consider the sensitivity of the front-end amplifier. It may be damaged because of the induction of the...
Hi,
The SAW doesnot contain any RLC component inside. SAW stand for surface acoustic wave. Inside the SAW their is a Glass or ceramic with 2 forks to transmite and recieive the ultra sound wave through the media.
The Q-value of SAW is very high. You can't implement it by RLC as the small size...
You are right, it can seem as special radar and it just detect the direction only not the distance and range.
The operation theory is also not different than Radar. Most of the Radar transmits a narrow beam of energy to space and record the time when it bounces back. The direction information...
Hi,
The lighning rods is a must for all outdoor electronic equipment. It can avoid the direcct damage from lighning.
In Radio system, you will have another issue on the low noise amplifier protection. The antenna is receiving the E&M signal from air. When the lighning happen, the antenna will...
You can buy a fiber modem to transmit your signal by fiber optics. It is expensive for both fiber modem and optical fiber.
I never tested before but it sounds you can use the RS-485 interface with twist cable to transmite low baud rate to 4KM. You may need some repeaters.
I hope it help
It sounds you are building a hot swap PCB and found the PCB will reset. Also, you PCB has a micro processor inside.
I suggest you check the peak current of your PCB. It seem when you put the board to the slot, the capacitor draw a lot of current make the voltage drop. The way you can do is...
Hi,
What is the application? By your spec, it sound you need a TWT.
The 2.4G TWT are usually used in the industrial heater or microwave oven.
You may check the www.rell.com they supply the TWT for industrial heater.
I hope it help.
