What is the Internal circuit diagram of crystal oscillator?
Ans. A series L R C in parallel with C' .
Why is the R-C oscillator also called a phase shift oscillator?
The R-C oscillator is also called a phase shift oscillator because the R-C filter creates a phase shift from input to output. The feedback portion of the oscillator (an amplifier) then serves to pump energy back into the filter.
What is the Algorithm for transpose of matrix in python?
Algorithm: transpose Input: a matrix M[x][y] Output: the transpose of M (a matrix of order y * x) allocate N[y][x] for r = 0 to x-1 // iterate over rows for c = 0 to y-1 // iterate over columns N[c][r] = M[r][c] next c next r return N

that u r friends regardless no matter what happens
What has the author Geoffrey R Harris written?
Geoffrey R. Harris has written: 'Loops and unoriented strings'
What is p equals r-c for c?
p = r - c r - c = p r - c - r = p - r -(-c) = -(p) c = -p

How do you use an array to show the commutative property?
If the array consists of r rows and c column, and the total number of cells in the array are n = r*c, then r*c = n and c*r = n so that r*c = c*r : which is commutativity of multiplication.
C equals 2pei R find for R?
Presumably C means circumference and R means radius? If C = 2*pi*R Then R = C divided by 2*pi
What is C equals 2r for r?
If: C = 2r Then: r = C/2
Why are raccoon enemies to bald eagles?
b/c they r!!!!!! b/c they r!!!!!! b/c they r!!!!!!
What is the letter of 3?
ab[C]defghijklmnopqrstuvwxyz. Exuse me but i think it is [R]. It is [C] or [R]. R is from th[r]ee. C is from [1 A] [2 B] [3 C]. ?
What is 27 c in r c?
presumably, r=27?
Formula of r form c equals 2pi r?
The circumference of a circle C is 2Pixr So solving for r we have C/2Pi=r
