Homework Statement
What is the frequency output of the mastergroup combining network for a signal of 552kHz to be translated using mastergroup 3?Homework Equations
Mastergroup Spectrum:
For AT&T = 564 - 3084 kHz
For ITU-T =...
This.
This can be easily done with microcontrollers.
Using the datasheet of the microcontroller look for features of timers, timers tend to be more efficient than for loops, this is for the PIC16xxx series. Don't know about arduino though
This is a cool project i might try this in the Proteus...
can an engineer become also a technician at the same time? Most of your work involve theoretical design but is doing ideal work also important? Because of some unknown losses/disturbance might be added to your system. Since virtual simulation today are a little inaccurate compared to reality...
2N7002 N-channel EMOSfet.
In an N-channel, when the gate of the transistor receives a high current, then the Drain and source terminals are open circuited. When the gate of the transistor receives a low current, then the Drain and source terminals are short circuited.
P-Channel is the opposite...
Devices today are getting smaller and smaller which makes the circuit layouts more complicated and hard to design. And knowing that microelectronics is just limited to the size of the atoms. Are people today now developing a replacement on transistors? Just like in the past when they are...

Homework Statement
How many grams of NaCl must you add to 750g of water to make a 0.35 molal solution?
Ans. 7.59g
Homework Equations
molality=\frac{mol_{solute}}{kg_{solvent}}
MW of NaCl = 23 + 35.45 = 58.45 g/mole

I already know how
first form three triangles with altitude three
total area = 1/2 (ab) = 1/2(3)(a) + 1/2(3)(b) + 1/2(3)(16) eqn 1
this will simplify to
\frac{ab}{a+b+16}=3
Then using this circle theorem
"If two segments from the same exterior point
are tangent to a circle...
may i take the OP's place?
im not sure about this problem and I am just referring to the image found on google image
1. it seems that one side of the triangle is the diameter of the circumscribing center so AC = 8*2 = 16
let
L_{B} = Length of the center of the inscribed circle to the vertex...
at the instant his father catches his son, they all have the same distance from since the son passed his father, hence:
d_{father}=d_{son}

f=\frac{v}{\lambda}
f=\frac{v}{2L}\mbox{ since }L=\frac{\lambda}{2}
v=\sqrt{\frac{T}{\rho}}=\sqrt{\frac{T}{\frac{m}{L}}}

So is it like this:
the previous charge of the energized capacitor is used to charge other capacitors. The previous energized charge is distributed to new charge of C1 and the equal charge of the series capacitors.
Q_{\mbox{energized C1}}=Q_{\mbox{new charge of C1}}+Q_{234}
Hence the new charge...
