This paper focuses on the experimental investigation of emergency siren simulator for small-signal power applications using Digital Storage Oscilloscope (DSO). Moreover, the paper also discusses the effect of various design parameters such as resistances and capacitances on the volume (i.e. magnitude) and frequency (i.e. tone) of siren simulator. The work, thus, proves the effectiveness of emergency siren simulator with variable volume and tone control; and improved circuit performance in terms of low power dissipation for real-time applications.
