Dear Warpspeed, I am very thankful.
I will study this pages. How wonderful dish microphones are!:!:

What is your idea about the appropriate speaker and related circuits?
Is there any speaker which supports this rang of bandwidth?
Thank you for your suggestion and introducing the book.

Thank you for sharing your experience with us. Do you have any other information about that project?
I need to use a microphone for recording sounds.
But I don't know exactly what features should this microphone have?

I want to use STM32F103 microcontroller. According to it's datasheet,it has 12bit ADC and 1MS/S sampling rate. Is STM32F103 a good choice?

Hello Dear Friends
I want to record and playback sounds in range of 0- 150 KHz frequency and I want to use any microcontrollers of ARM series.
I have some questions:
1. How much should sampling frequency of ADC be?
2. Can I use ICs like VS1053? Does this IC support 0-150KHz frequency?
3. Can...
Re: How to Simulate Swiching Power Supply
Hi BradtheRad
what do you mean by animated interactive simulator?
I searched about it but I couldn't understand it.
Hi everybody
I want to start working with SMPS (Switching Mode Power Supply) But I don't know how I should start.
would you please show me the way?
I prefer to start by a simple circuit and simulate it at first then I test it in practice.What is your idea?
What is the...
I just know for measuring AC voltage and current we use multimeter or oscilloscope which adjusted in AC mode,is there any thing more than this?
My question is, for example if we want to apply voltage across a resistance there is two junctions which we can connect the probes to them,but about...
Hi
Thank you for your participating in this topic.
Interesting…
A new question is coming to my mind,actually I know this question isn’t related to this topic but it comes to my mind suddenly after thinking about the properties of water.
The question is:
Why is intensity of electric shock...
I just want to know what is the resistance of drinking water?
How much should it be? Why dosen’t multimeter show a specified amount and just keep changing and changing…
What dose the resistance of water depends on at a temperature of 25 degrees Celsius?
For example does it related to the...
I want to measure the resistance of water. How can I do it?
once I tried it by puting the probes of multimeter in a glass of water and it showed the resistance about the range of 50kΩ-800kΩ and it wasn't constant, it went up and down and didn't have specified amount!
What is the reason of this...
Yes I mean "electric fire".
In fact I want to know that what is an electrical coal, which use for hubble bubble, made of?
I am searching for it's structure.
Could you please help me
Thanks in advance
Hi my friends
I want to make an electrical coal which has the ability of being charged for some hours or use the power directly.
What is it made of? and how can I build it?
What is your suggestions?
