hi ,
i am new member and i need your help
i need 2 mini circuit one for (pwm)and second for(pcm)
i use multisim 10​

 

You need to expand:

PWM:
- sample rate
- input range
- output amplitude

PCM:
- sample rate
- resolution
- input range
- output amplitude

Is this coursework?

 

my teacher dose not give me this information
i need onley design

 

I have moved this thread where you are more likely to get the help you need.

Before you can design anything you need to set design specs. It is part of the process.

Refresh my memory please, what is PCM?

 

hi ,

i need (pcm) circuit

 

Please use your existing thread to ask questions. Multiple threads only confuse the issue.

I have merged your two threads.

I looked PCM up on Wikipedia.

http://en.wikipedia.org/wiki/Pulse-code_modulation

You will need to decide on byte size. Again, you need to provide the needed information first before anyone can help you.

I have changed the title of your thread to give people more idea what is needed to help you.

Have you read these out of the AAC eBook?

Pulse Width Modulation

Chapter 13: DIGITAL-ANALOG CONVERSION
