Discussion Overview

The discussion focuses on designing an astable circuit using an operational amplifier (op-amp) with specific control over the threshold voltages (TH, TL) and output voltages (VH, VL). Participants are exploring the requirements and parameters for this design, potentially using simulation software like Multisim.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant seeks assistance in designing an astable circuit with controlled variables for output and threshold voltages.
  • Another participant requests clarification on the meanings of the variables TH, TL, VH, and VL.
  • A subsequent reply defines VH and VL as high and low output voltages, respectively, and TH and TL as the time for charging and discharging.
  • A participant expresses gratitude in advance for any help provided.

Areas of Agreement / Disagreement

The discussion does not show any consensus yet, as participants are still clarifying terms and requirements.

Contextual Notes

There may be limitations in understanding the specific context or definitions of the variables involved, as well as the assumptions regarding the design parameters.

Hi every one, i want to design astable circuit using op_amp and i want control TH ,TL,VH and VL

for example VH=x ,VL=y (x,y ara variables which i can cotrol them )
TH=m , Tl =n (m , n ara variables which i can cotrol them )

using multisim or any simulation program
 
Engineering news on Phys.org
What are TH, TL, VH and VL?
 
VH ,VL(high,low output voltage)

TH,TL (time charging and discharging)
 
i will be grateful if u help me
