Homework Statement What is the bandwidth of an AM signal if the modulating signal is x(t)=cos(2pi70t)+cos(2pi90t) and the carrier frequency is 10kHz? Homework Equations The Attempt at a Solution The carrier frequency is irrelevant because it just means the signal's spectrum is...

That makes sense, I'm not sure why I got so bogged down in the difference in the symbol. Thanks.

I am looking for help on a schematic for a 12 transistor CMOS SRAM cell shown below. I understand how to implement the inverter and transmission gates and how a tri state inverter works, but I am confused when it comes to inverting the input of the buffer and how to tie it all together. Thanks...

I was tasked with finding the worst case noise margins from two input characteristic curves and I think that in most practical cases it is the same as finding the noise margins for one curve. I thought that the noise margins may be measured as a combination of the two curves doesn't seem likely...

I know how to find the static voltage transfer characteristics (output low voltage, input low voltage etc) for one input gates like an inverter from the graph of Vout v Vin. My question is how do I apply this to gates with two inputs? These graphs have two curves by keeping one input constant...

Just a quick concept check. It seems to me that all instantaneous (memoryless) systems are causal because the output of a memoryless system at an instant t depends solely on the input at an instant t, and causal systems are systems whose output depends on past and present inputs only. Is this...

(abc)' + abc = 1. There are only 2 possible values for abc, and they are 0 and 1. So it is very obvious that if abc isn't 1, then (abc)' is, and vice versa. So 1 or 0 = 1, 0 or 1 = 1. To prove that a'b'c' + abc = 1 isn't always necessarily true, you can construct a truth table with a b c a' b'...

Ah. A silly mental error as I was using an applet to find the value for z that matched the probability but with a curve that had the mean and standard deviation of the original variable. Thanks for helping me again Billy Bob!

Homework Statement Let X1,X2,...X10 be independent normal random variables with mean 10 and std dev 4. Let Y = X1+X2+...+X10. Let X be Y/10. What is P(X < 8) Homework Equations E(X) = 10 and Var(X) = 42 / 10 = 1.6 std dev of X = 1.6.5 = 1.26 The Attempt at a Solution To convert...

That is so much better. Thanks. The organization of my book is pretty terrible, I'm just finding that equation now.

Homework Statement Find E(XY), Cov(X,Y) and correlation(X,Y) for the random variables X, Y whose joint distribution is given by the following table. X 1 2 3 Y -1| 0 .1 .1 0| 0 .5 .6 1| .2 0 0The Attempt at a...

Hello, I'm tasked with building a queue from as many stacks as I'd like, trying to get the fastest implementation possible. The best I can think of is using two stacks and as you enqueue items you push them on the first stack stack, but every time you want to dequeue if there are n items...

Homework Statement 5 men and 5 women are ranked according to exam scores. Assume no two scores are the same and each 10! rankings are equally likely. Let random variable X denote the highest ranking achieved by a woman e.g. X=2 means the highest test score was achieved by 1 of the 5 men and the...

I am now almost positive the first tree is correct, but what about Preorder: DBACEGF Inorder: ABCDEFG I have: Root is D has left child B right child E. B has left child A right child C. E has left child null right child F. F has left child G right child null.
