Hello guys,
I want to measure the spectrum of a signal, but the input signal is continous time. could someone please help me.
Thanks in advance for any help.
hye guys,
I'm trying to measure the frequency spectrum of my simulation model. Unfortunately, the model's output is in continous time, so I cannot use the FFT block. Any suggestions how this can be done?
Thanks in advance for any help
Thanks for the reply. I think tilt sensor is not suitable for my case because I want to detect if someone moves the bicycle. Thanks a lot for you suggestion about the movement sensor
hye guys, i'm to build a device that detects if a bicycle is moved from its rack. I wish to use accelerometer. Is this relevant? will an accelerometer do this job?
Thanks in advance for any help
hye guys, I'm looking to model a class d amplifiers in simulink, any idea on how I can do that? I had already built the PWM generator, but I don't know how to connect it to the half bridge configuration (MOSFETS). I really need help here as I had been stucked doing this for days. I also attached...
hye guys,
I'm trying to learn on how to program using this matlab thingy in Simulink. Is there any website that provides tutorial in writing this kind of code?
thanks in advance
hye guys,
Can anyone explain to me what is bipolar and unipolar PWM? I had search trough the net and couldn't find anything.
Thanks in advance for any help.

hye guys, i'm trying to use the comparator in simulink, but i couldn't make it work. I'm trying to compare two voltage from a counter and ADC. Can anyone please help me to use the comparator in simulink? and if you guys happens to have any other idea on how to design a PWM generator, please let...
ye guys,
I'm building a comparator with hysteresis using an opamp, and I follow whats in the datasheets (LM324). Below is the circuit diagram of my design, and the output signal wave. I need to build a comparator which output voltage is +2V and -2V, and the hysteresis value Vt=1V. From the...
the min and max frequency is not given yet, its given later during the lab.
The method of doing it is indipendent, and theres restriction in designing it as long as it meets the requirement.
thanks
hye guys,
I'm looking to design a Voltage Controlled Oscillator (VCO) that meets the below requirements :
-output voltage should be periodic but doesnt matter what shape
-should adjust its frequency in response to input voltage which is 1V-2V.
-input impedance should be more than 10k ohm and...

I should use the LM741. It is the requirement. The purpose is not to make a fully power efficient circuit, but it only want to reduce the power consumption. Got any idea on how to do it? Thanks
@ebbeyromy
thanks!
