noise in pspice! please help!

[sagh]

I would be grateful if anybody tell me how can I add a noise source in pspice, I have a voltage source and I want to apply noise to it. Please Help!

you can use "PWL Sources" to create a noise source of your choice. Add this in series with your regular voltage source. You can use Place >PSpice Component>Source> PWL Sources to quickly create PWL source mimicking noise.

You can also use alternate way to create this using E devices, - refer a detailed step by step instruction at https://www.ema-eda.com/EMABlog/EMA...l-Adding-a-Random-Noise-Source-in-PSpice.aspx

Basic concept of these two approaches remains same.
Hope this helps.
