The electrons move back and forth between the capacitor and the inductor. Compare this movement with a mechanical pendulum. It can move much more than the movement you used to push it. It is the same with the electrons.
Can you find (or write) software that simply sends and receives data via USB at each computer? If you can gain control over such communication then you might get a cluster concept to work, regardless of what OS they use. Then you can add routines that make them cooperate at doing whatever operation you wish. Example, to make them play chess, you
I'm just about to get my Spartan-3E to read an optical sensor mounted next to the harmonic balancor so I can display the engine RPM. Thinking ahead, I would like to someday implement electronic ignition using COP (a coil over each plug) after the computer learns how to read the MAP, O2, TPS, baro and so forth. I would
You have a serious confusion with RB1_bit and EncoderA_bit respectively RB2_bit and EncoderB_bit. Encoderxx is defined as alias of the RBx, but should be a variable holding the previous input state. Apart form this problem, the code should work. There's a possible complication with bouncing encoder outputs, RB1 and RB2 should be better copied to
Redraw your schematic such that every "wire" segment is an inductor, each device has a capacitor from every pin to every other node in the circuit (you may choose to stay local, for convenience) and your resonant behaviors will suggest themselves. Subject to appropriate scaling, and damping and so forth. And of course those cute little ideal-gro
transformer start to produce a noisy sound like"tik-tik-tik" and voltage change beetwen 40-45 The irregular operation could be unwanted 'hiccup' mode, or maybe a case of squegging. It works okay for a few cycles, then a momentary lockup. As this repeats back-and-forth, the transformer can make audible noises.
DC Blocks which you place in labaratory is actually real capacitors which you use in circuits to prevent unwanted signals from entering to either port(terminal) of your device. Those components will be replaced by real inductors and capacitors serving the same purpose in your circuit. When you talk about realistic, things get much more complicate
Hi all, I designed a 12bit DAC based on R-2R topology in a 0.18um CMOS tech. It is 8+4bit segmented. The sizes of the switches are increased in a binary weighted manner as the current drawn from each consecutive higher significant bit is going to be double. So, the switch of the LSB is 1 unit, LSB+1 is 2 unit so for and so forth. The segmented p
Hi there! I'm working on a home-made project with a servomotor using Basys 3 . I need to control my servomotor in that way that it can rotate 90° back and forth several times. My servomotor is a SG90 9g Micro Servo and I'm tryng to write a code in VHDL to control it. The problem is that i don't know how to make the div

The pdf has equations which appear to show ratios between components, but they do not give specific working values. Fortunately I like to play with simulations, and I spent some time experimenting with your Chua oscillator. The goal is to start L & C2 oscillating back and forth at their resonant frequency, while C1 introduces a different frequency.
I just wanted to know if in a BLDC motor i am driving and in the initial phase of testing may be i want to try with different switching. In case my switching is wrong and the machine halts or moves back and forth. In these circumstances it is always that mosfet fails, if in case i don't stop switching within some time. I know there is no schematic.
The thread below is about driving an ultrasonic transducer. I posted a driver circuit there, designed to send full supply voltage back and forth through a series LC, by detecting its resonant frequency automatically. The concept may be adapted for your purposes.
It's a good idea to portray Rsource upstream of the filter, as a reminder of its presence. If it were absent entirely then enormous AC current passes back and forth through C1 (possibly other sections of the filter). In addition, by varying Rsource it is a way to influence the sharpness of the filter curve.
dc-dc converter circuit that will be able to convert 30v/2a into 12v/5a Theoretically a buck converter can do this. This simple simulation is based on using ideal components. 144672 The LC input filter draws smooth current from the supply. Internally the converter has waveforms peaking ove
For 2 phase Buck, the normalized ripple current is reduced to 25% max at duty cycles of 1/4 and 3/4 and is null at 0, 1/2 and full duty cycle. For a 3 phase Buck the max ripple current is 16.7% with nulls at 0, 1/3, 2/3 and full duty cycle. For a 4 phase Buck the max ripple current is 12.5% with 5 null duty cycle points for ripple. and so forth.
I'm working on the processing of raw FMCW radar data. In my case the radar works in the GHz band (I have 187 frequency points starting from 6.014 GHz and ended with 7.76GHz) and the data that I collect are organized in a complex-double numbers (I&Q) matrix per each couple tx-rx antennas. Unfortunately the
I am going to connect my FPGA board to my PlayStation controller port. The FPGA shall monitor the data going back and forth between the console and the controller. The basic concept on how to get the signals on the FPGA board (physically) is done. I have a basic question, the signals being monitored are going to be between 0-3.3V. However, what
Pow is not OK. Pow is a floating point function. Besides the fact that mega doesn't have dedicated FPU (that makes compiler to create a huge amount of code for mega's integer ALU, something about 2K of memory) the floating point numbers tend to be erroneous, so when you do 16^2 you get not 256, but 255.99997 (not exactly this, but similar),
just re-checked it again...when i loosen the battery in the body..back or forth some time it lits up though ... but still not pefect working ... any tips.. thanks Hi, The manual says something about "Before turning on the transmitter, check that the throttle stick is pulled completely backwards
