Discussion Overview

The discussion revolves around the construction of a signal alternator that can switch between two input signals, V1 and V2, at a specified frequency. Participants explore various components and circuit designs that could facilitate this alternating output.

Discussion Character

  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant suggests using bilateral switches, specifically mentioning the 4016 MOS quad bilateral switch, depending on the voltages of V1 and V2.
  • Another participant inquires whether V1 and V2 are DC signals and proposes creating a square wave generator circuit with adjustable parameters.
  • A different participant mentions that analog switches and relays are obvious choices for the task.
  • One participant describes a 2:1 multiplexer as a potential solution, explaining its operation and cautioning against using a digital multiplexer if the inputs are not logic values.

Areas of Agreement / Disagreement

Participants present multiple competing views on the components and methods to achieve the desired signal alternation, with no consensus reached on a single solution.

Contextual Notes

There are assumptions regarding the nature of the input signals (DC or AC) and the specific requirements for the frequency of alternation, which remain unresolved.

Suppose I have 2 input signals V1 and V2,
And I want my output signal to alternate from V1 to V2 and so on at a particular frequency.
Any idea what components can help me to achieve this goal??

Thank you

Depending on the voltages of V1 and V2, you might want to look into bilateral switches. The 4016 is a MOS quad bilateral switch.
 
Are V1 and V2 DC signals? If so, you just make a square wave generator circuit, with an adjustable high value and adjustable low value (or adjustable amplitude and adjustable offset)...
 
Analog switches and relays would be the obvious choices.

Thanks for the suggestions
 
Sounds like a multiplexer

A 2:1 multiplexer will have 2 inputs, a select line, and a single output. The output will be the selected input: that is, if there is a logic "0" (ground) on the select line, the output will be input 0, and if there is a logic "1" on the select line the output will be input 1. There are different types of multiplexers--don't use a digital MUX if your inputs are not logic values (I presume they are not, or you would not have asked the question).

This way, whatever your inputs are--DC, AC, audio, etc--you can alternate between them at a desired frequency simply by applying the desired frequency to the select line.
