Hi isobel. When I worked in electronics manufacturing we had 3 production lines. Each product used over 900 parts. The machines on the line could construct a 900 part board in 40-60 seconds (this is pritty slow on average). 

Although part suppliers could provide next day parts, many cpu and fpga chips are hard to source with long lead times based on the quantity we needed. So order long lead time first, then everything else. Once batch one is started, batch 2 is ordered for. The idea is to get min overlap in stock but never a gap. Plus 20% extra ontop of what you need incase something goes wrong I.e. damaged part etc.

Why do manufacturing businesses hold stoc ?

Hi Shay, do you remember the different types of operational amplifier configurations? 

Your transfer function is incomplete so difficult to say, but have a look at the following link. Gain and phase angle and standard calculations so it's about understanding how the op amp config alters the input signal. 

This link is very good:

Pro tip: phase angle is much easier calculated in polar rather than cartesian. You can use the "pol" function on your calculator to do it. Look up how to convert one to the other if you dont remember 

Maths

If you were given a transfer function,   ( ) =2/  (s+ ) (s+ ) and that the frequency, w=2 rad/ . How do you calculate the gain and phase angle of   ( I

Hi Abdullah, what exactly are you trying to do. Or what do you need help with? Is it digital systems within the context of industrial automation?

Hello everyone I am looking for anyone who can help me in the digital design engineering automation . Thanks

Say you have a x by y array that's made up of 4 smaller s by s arrays. The max pool is like a filter that returns tha max value of each s by s subarray thus creating a smaller 4 x 4 array in this case. 

A good way to aid your understanding is to forget about the larger neural network for a moment and create some little example arrays. Then try to write a program that will create a max pool based on your array examples.

The following wiki has some good information: https://computersciencewiki.org/index.php/Max-pooling_/_Pooling

How does maxpooling in neural network

Think I answered one of your questions before. To recap my last comment: sololearn and flowcarts are your friends. 

This really depends on which programming language your going to use, but they are all kinda the same. Certainly they follow the same principles

I'm only going to give you a hint. There is a function called 'range' than returns all the integers between range x and y. Do a little revision on this and see it you can use the range function to return integers from something like x=5 and x=10. 

Computer Science

Write a program that displays all the perfect numbers in the range [a, b], where a and b are two integers read from the keyboard.

Have you checked out the website sololearn? Good for programming lessons to give you the language skills needed. 

But in general, use a structured programming approach (I.e. draw a flow chart). Once you have your chart you just need to translate each element to code and your down.
