hi guys
I am attempting to solve a problem that has me scratching my head. I have a small connector PCB with one 8k resistor present. The connector is four way with the resistor terminals being the two inner pads. The outer two pads are short circuit together.
I solder two wires on the...
hi there
I am currently working with linear flows and using a ultrasonic setup to determine the speed of sound in a linear gaseous flow. But I would like to know more about the speed of sound in a vortical flow. Unfortunately I haven't been able to find any good book with regard to my topic...
hi
I know the Fourier transform of a lorentzian function is a lorentzian but i was wondering if the Fourier transform of the second derivation of a lorentzian function is also a second derivative of a lorentzian function
Thanks
hi
the differential equation i am attempting to solve is:
\frac {dP} {dx} = \frac {gP} {1+P/Psat}
here is what I have done:
\frac {dP} {dx} = \frac {gP*Psat} {Psat+P}
divide both sides by \frac {Psat+P} {gP*Psat}
to get:
\frac {Psat+P} {P*Psat} \frac {dP} {dx} =g...
what does normalization mean?
for example say i have the guassian input as :
A(0,T) = \sqrt{Po}*exp(-T^2/2To^2)
then we can normalize it by defining t=T/To and A(z,T) = \sqrt{Po}U(z,t)
Po= peak power t= normalized to the input pulse width To. if the peak of the pulse is...
Hey guys, I have a good job lined up for me after I graduate with a good company, i am currently 8 months away from graduation. I have a diffcult desicion to make about my final year project. I have been offered projects from two companies and one of them is the one i start working for at the...
Hi
i was wondering what's is the difference between electromagnetic waves and fields or is a field just a number of electromagnetic waves. also i was wondering is it possbile to have an electromagnetic wave where there is only a magnetic field and no electric field and vice versa
Thanks
Hi
if i have a voltage supply of 100V connected across a 66 ohm resistor which has a power rating of 155W. then P=V^2/R=10000/66=151W but say if i had the same situation except i add another resistor in series to increase the resistance of the overall circuit by adding a 100 ohm resistor...
well i connected a 0.1uH inductor to a signal generator which generated 5V ac voltage and then i added a resistor connected to the inductor and ground.
then i measured the voltage across the 10 ohms resistor on a oscilloscope and at was the same as the input so that's why i wondering if i...
hi
i was wondering if we would treat inductors and capacitors as short circuits for AC voltages. i am aware that there is a 90 degrees phase shift in a RC or RL circuit with an ac voltage but the phase shift only applies to the current.
thanks
hi there i am looking for monochromatic colored filters like on the picture on the following web page:

(preferably with no reflectivity)
but i have had no luck trying to find them while looking on google
hi
i bought a machine which determines led colours by measuring intensity for a product.
the product has three leds:green,red,orange. the equipment works well for the green and red leds but fails most of the time with the orange leds. i looked up wavelength values for the colours and i...
thats super cheap and awesome bassalisk i going to order one after i test the one i am building and colin thanks for the tip i have ordered a 18-pin IC pin socket. do you think it would be safe to put the cct together on a breadboard and connect to my pc via the RS232 female connecter
