Reviewer 2 Report

The paper presents an interesting solution of the generator, the advantages of which are: the simplicity of the solution, the possibility of implementing it from relatively cheap components available on the market, the possibility of independent adjustment of the amplitude and frequency of the generated signal. This generator can be an interesting proposition for DIY enthusiasts as well as for engineers. The paper contains the necessary theoretical analyzes as well as the results of generator measurements. 

I have only one comment, namely the publication does not explain how to apply the proposed generator in capacitive sensors, as the title of the publication suggests.

Dear Sir/Madam

The authors have added the circuit to be applied for Capacitive Sensor Interfacing in Section 1 (Introduction).

Reviewer 3 Report

The paper titled "Duty-cycle Electronically Tunable Triangular/Square Wave Generator Using LT1228 Commercially Available ICs for Capacitive Sensor Interfacing " describes a practical implementation of an analog circuit for driving sensors.

The title mention that this circuit architecture is developed by the authors to drive "Capacitive Sensor Interfacing" but nowhere in the paper a such sensor is presented.

I am curious why the Authors want to mention in the title the "Capacitive Sensor Interfacing" while there is no example of such sensor in the manuscript.

Moreover, no circuit implementation is presented in the paper.

The only circuit concept is presented in subsection 4.2.

I suggest that the authors to:

- clarify the Title of the paper;

- to add a photo of the actual circuit implementation of the circuit (e.g. a breadboard, a PCB etc.);

- to add a photo of the actual experimental setup (e.g. including bench power supply, oscilloscope connections, probe settings, etc.);

- to add a schematic showing a possible utilization of this circuit for "Capacitive Sensor Interfacing";

- to improve the References, by citing for example this work:

https://ieeexplore.ieee.org/document/8792895

which has strong merit in scientific community.

If the Authors comply with all those requirements, the paper quality will be improved and will gain more scientific sound for readers.

 

Best Regards,

The Reviewer

Dear Sir/Madam

The suggestions of the reviewer are as follows:

- clarify the Title of the paper;
The authors have added the content of the circuit to apply Capacitive Sensor Interfacing which is in Section 1 (Introduction). 

- to add a photo of the actual circuit implementation of the circuit (e.g. a breadboard, a PCB etc.);
The authors have added the figure of the real implementation of the proposed circuit, as shown in Figure 12(b).

- to add a photo of the actual experimental setup (e.g. including bench power supply, oscilloscope connections, probe settings, etc.);

The authors have added a photo of the setup for the experiment, as shown in Figure 12(a).

- to add a schematic showing a possible utilization of this circuit for "Capacitive Sensor Interfacing";

The authors have added a schematic to apply Capacitive Sensor Interfacing, as shown in Figure 1.

- to improve the References, by citing for example this work:

"https://ieeexplore.ieee.org/document/8792895" has been referenced, as shown in [8].
