Not a problem, many thanks for the help!

Hi, any thanks for the response. The actual problem we're having is converting the x(t) = r(1-cos(t-psi)) as the trigonometric Fourier series. We can use the MATLAB simulations etc but the first conversion is our issue. Many thanks, Brad

Homework Statement Homework Equations All Fourier series trigonometric equations. I think we are required to use sigma function, integrals, etc.[/B]The Attempt at a Solution We are currently working through our Fourier series revision studying integrals of periodic functions within K.A...

Hi all, A few basic questions regarding inductors really. I'm just doing a bit of reading into these little beauties and trying to get to grips with the workings. My questions are: 1.) Do inductors generate larger magnetic fields with DC or AC? (Providing the same current and voltage) 2.) If...

Many thanks for all the helps guys. I have put the bulbs in series after the emitter of the transistor and used the same position transistors. I tried my previous set of resistors (stated in the original post) on a breadboard and the circuit works. I used a matrix board previously but for some...

Apologies, I got you!

I see. Just a question though, how did you come to the 60K resistance value number? I will try this and see what it yields.

I'm not too sure on what amp each battery is but I do know that I'm reading 4 Amps on the multimeter. This did seem very high to me to be honest.

Hi guys, Right a really simple question here and I'm missing something really basic. I have a simple LDR circuit that I can't seem to get working. I'm completely adept at Electronics and it's use is just for a small project I'm working on in my spare time. Attached below is a picture of the...

Why not! Could you show me your solution? I'm really not getting it!

Sorry guys just been told that we can use a 3 input NAND and solved it. C and B connected to NAND 1 C and A connected to NAND 2 B and A connected to NAND 3 Then all 3 NAND's connecting to a final NAND Many thanks for all your help! B

Hi, I have already designed it with AND and OR gates however I can't understand how to convert this to NAND

Hi. Yes I already have P=B.C + A.C + A.B Isn't this the simplest it can be whilst conforming to De Morgan's laws?

Homework Statement Hi everyone, Very new to this forum so please bear with me! I have an assignment as part of my engineering course that I seem to be struggling with so I'm wondering if I can grab some help. Basically I have a water tank that feeds three separate processed (A, B, C). When...

Many thanks Bystander.
