Hello,

My name is Paul, I've been doing a lot of googling this morning into electronic circuit simulators which lead me to this site. It looks great and the fact that there is a dedicated forum resulted in my signing up..

I've had a quick play with the application and it appears very user friendly. My question is around whether the app will be able to support what I want it to do.

I have an existing (undrawn on here yet) circuit that I need to analyse.

To provide a synopsis of the issue :-

The cct consists of 7 beams (light) and one inductive sensor. I will need to individually monitor the time they are on/off and then construct a logic cct to flag the outputs of the timings to some form of visual indicator (light stack most probably).

Is the functionality of the app able to assist me perform this?

Regards,

Paul.

Welcome Paul,

Yes, CL can help you.

However you must understand that you will have to interpret the outputs of your simulated circuit in terms of waveforms and/or tables of figures. You will not see visual indications such as LEDs lighting up or DVM displays showing numbers.

You will also have to get into the idea that you can represent any real world phenomenon in terms of electrical signals.

For example, an interrupted light beam may be represented by a voltage source that that switches from a 1 to a 0 or maybe from a wobbly 9 - 11V (a sine wave with a DC offset) to a wobbly 1 - 2V to represent some noise on the beam due to stray light etc.

CL has several publicised user models of things like photodiodes, phototransistors and photoresistors as well as some simple and behavioural inductor and transformer models which can be used to model your various sensors. You just have to think how to represent your real world inputs in terms of DC, pulsed, piecewise and behavioural sources and components.

Then you can model your sensors, buffers, amplifiers and ADC or DAC components and any logic processing using the built-in supplied components (primitives) of CL.

Does that help?
