Okay, I've got a differential amplifier biased by a constant current source at the source of each mosfet. There is a resistor R connected to the drain of each transistor and those resistors are also connected to a +5 DC. The second stage is a common source amplifer. The drain of transistor 2...
The problem I am having is that when H(s) and G(s) are multiplied together, a zero is introduced because of the feedback loop. The location of this zero changes as the gain changes. So the gain cannot be varied without moving the zero. Thus every value of gain produces a different root locus.
I had to use state-variable feedback to design a position control system for a motor. I have to design the controller using root locus methods.
The gain that is varied is located in the feedback loop as shown in the picture.
I am completely lost as to how to generate a root locus with the...
I had to use state-variable feedback to design a control system for a motor. I first designed a deadbeat controller, which was pretty easy.
But now I have to design another controller using root locus methods.
The gain that is varied is located in the feedback loop as shown in the picture...
motherboard design and microprocessor design is two different worlds.
motherboard design is all about putting the pieces together and laying everything out properly.
the layout is a major pita.
microprocessor design is all about putting components in a specific order to make the micro...
I designed a circuit that has an analog signal conditioning portion, and a digital circuit to make some measurements on the signal.
The analog circuit is powered by 15V supplys, thus the output is a 0-15V square wave. The digital circuit needs a 0-5V input. I tried using a voltage divider on...
There are actually more wheel speed sensors besides the ones I discussed my module must work with. I cannot decide what sensors are used, I have to work with what's already existing.
I don't quite understand the difference between vehicle ground and the DAQ ground either. The DAQ does ride in...
Thanks for the tip with OrCad, I'll try that next time.
These signals are coming from wheel speed sensors. The low-amplitude signal is from a passive sensor. The passive sensor varies with the velocity at which the teeth of the gear pass the sensor as well as the air gap. The air gap should...
This is a horrible representation, I had to make it in paint because I can't post OrCad schematics on here. Should be enough relevant information though.
I designed an analog circuit that transforms a couple of different incoming signals into a digitally compatible signal. I was recently informed there will be a grounding issue at the front of the circuit. The incoming signals will be from a variety of sensors. The first part of my circuit is an...
I was designing a circuit to determine frequency of signals using a counter as the main part of the circuit. However, I was just informed that period must also be measured or have the circuit perform one of the other.
Are there ICs that are able to determine the period between rising edges? If...
Need to design a digital circuit that determines the frequency of incoming signals. Incoming signals will vary, but all will be converted to a 0-5 V square wave before going to the digital portion of the circuit. The current idea is to have a counter to count the edges for a certain period of...
Here are a few examples of some of the signals I will be dealing with:
sine wave ranging from 0-50 V up to 5KHz
square wave with DC offset
sqaure wave with extended 'high' times looks like this """""""""|____|""""""""""""""""""""""|____|"""""""""""""""""""""""""""""
the frequency at which...
I've got to design a signal conditioning circuit that takes in a few different signals and converts them all to a standard signal. The overall purpose is to determine the frequency of the individual signals.
Any ideas on how to make a variety of signals into one standard signal? Preferably a...
