Hi all, I realised that my approach to HDL development is very inefficient. I am still uncertain on how some of the constructs will be synthesized and have to go back and forth between the Synthesis tool ( VIVADO ) . But waiting for VIVADO or ISE to synthesise my design each time is painful. I am wondering if anyone who is in an environment w
Hi I'm looking for a pre-built x86 board with the following rough specs: x86 - i3 ish level of processing inc Floating point (32 bit is fine) low power (board powered via USB) ram up to 64MB flash or rom for application on boot up. 2x USB 1 for input other for output dedicated capable of running forth ideally or linux if I must programmable via w
I'm thinking of an earphone used with old-fashioned pocket transistor radios. A coil next to a steel diaphragm, 1/2 inch diam. (Maybe the diaphragm is magnetized, one face north, the other face south.) Run AC through the coil. It moves the diaphragm back and forth. The sound travels to a tiny hole at the other end. To do sonic welding, I think wil
Back and forth (load/unload) switched capacitors can be used to replace resistors in analog systems (e.g. filters).
Does that mean i measure S21 since i use two different terminal/port? no. antenna is single port component. an amplifier and filter is dual port. whatever device (antenna, filter or amplifier) which needs two network analyzer ports to connect is two port and so forth. Did you use the same antenna for both signal generator and spectrum analyzer? A
Hello House, How is USSD menu implemented. for example, when you dial *123# from a phone, how does the ussd application get to responds with a m menu like "Welcome to MyService 1.Balance enquiry 2.Sport news 3.Weahther Report and so on and so forth." I have already implemented the handlers for various command such as Bind, Submit_sm, Data_sm
Your graph doesn't say which trace is which, but I'd assume the square blue trace is input since it's ideal looking. Then the other, presumably output, says to me that you've got no ground connection and no load, and are just shuttling input charge back and forth to the output through some device that's attached to +1.2V and leaking enough to set
The problem is probably more a system design problem. There are a few poor design practices in the code. 1. You generate clocks with logic. Instead you should generate clock enable signals and use the same system clock all over. 2. Using buttons without debouncing them. When you press a button it actually bounces back and forth between 0 and 1 go
Hi, I'm trying to use an if else statement in microC to toggle an LCD screen between two states. Unfortunately I cannot get this to work, The code under the if statement cycles between 3 different messages and when the button tied to RB7 makes RB7 go low, it's supposed to make the screen display the string "Screen Toggled". What is hap
In a recent thread you asked if the oscillator transistor in a radio transmitter mechanically oscillates! I answered that the transistor is in an oscillator circuit with no moving parts. I said the electrons go back and forth. Now you are asking about how does a radio transmitter work, but it is obvious that you have not looked in books or in G
Unless you have a round room, I don't know why you would have the bot run in a spiral; do YOU vacuum the floor in spirals? Why not run it like a Zamboni or a lawn mower? Have it first find a corner and then just go back and forth in rows.
With DC current, the electrons travel around the loop in one direction. With AC current, the electrons alternate back and forth in the loop.
Do you mean, you want to implement a motion scheme for the existing mechanics? It's now moving continuously forward but want to drive it forth and back? Besides motor and drive electronics specification, you need also to check that the mechanical setup is prepared for the inertial forces involved with this operation mode. Regarding qualificat
hii, i am designing an application in which i need to turn motor shaft BACK AND forth from 0 degree to around 190 degree (any fixed angle between 180-210) at HIGH SPEED AS POSSIBLE...which motor would be best in terms of Speed??..DC,SERVO,STEPPER??. angle accuracy is not necessary..jst need little more than 180 degree...help me.
start v2=0 end v2 is computed using dc voltage divider equation inbetween, square wave pulses travel back and forth on the transmission line, with diminishing amplitude on each bounce. The reflection coef at load is simple to calculate, as is the source. Just be mindful of possible sign change at one of the ends of the line!
could you specify on the graph which belongs to S11,S21 and so forth. thanks.
You want to send SPI data back and forth between two points, right? I'm afraid I don't understand your question. The fact that the SPI data represents audio is irrelevant. Maybe you can give us a better description of what you're trying to do.
We have one of the attached Copley DC Servo Amplifiers. It is not functioning and we need to find a replacement. Anyone can suggest a proper replacement? It drives a DC motor (90-110V DC and 20A). Motor turns back and forth from a "H" power bridge using a triangle shape current when up and down buttons pressed. Feedbacks are motor speed taco signa
Winding back and forth, no cross-windings as far as possible.
What is the best way to unsolder a bunch of 0.100" header strips and DIP IC's without damaging the PCB substrate/lifting pads?? I have tried solder braid and I can get 90% of the bulk off but the small amount left can can be removed. I have tried hot air rework but on 20+ pins you need to sweep back and forth and the PCB heats up to much before
