what is the differences between the microcontroller and microprocessor ?

How about this:mizel said:1. Write a pseudocode program that computes whether or not a point A is located inside a triangle specified by three other arbitrary points (X,Y,Z).
(To solve this, compare the lengths of the lines AX, AY, and AZ with the lines XY, YZ, and ZX. If any of the A lines are longer, the point A is outside the triangle.)
What you say above is true, but it is not a complete (or adequate) solution to eliminate all the points that are outside of the triangle. The shape this would check would be three arcs that touch at the vertices of the desired triangle.
For example, imagine an isosceles triangle, the line drawn from one vertex in the direction of the bisector that is the length of the legs. This would lead to a point that passes the above test but is in fact outside of the triangle.
Anyone know a clever way to do this?
By "clever" I mean one that uses a minimal number of calculations (i.e. doesn't use any angles). I can think of several ways to do it, but they all resort to using angles at some point.

aryajur said:Here is an interesting question. The opamp shown in the circuit has the open loop response given as shown, so it has enough phase margin. When the opamp is connected in the feedback as shown, it becomes unstable for a particular Vin as Vin is increased. Why does that happen?

I think that there's an extra added pole due to the LPF effect of R and C of BJT
If I could connect a hv voltage-sending oscilloscope between neutral and phase on a balanced 460vac 3-phase system, what would be the peak value of the waveform?
Heres one:
Use a 2 input mux , and an inverter.
Can you make the 2 input XOR gate?
