The system consists of a 555 timer working in an astable mode which provides an output pulse with a 50% duty cycle. The system consists of a total 4 stage multiplication stage, with each stage consisting of a capacitor, 2 diodes, and a MOSFET as a switch. The diodes are used to charge...
When the mobile phone signal is detected then the output of U1 becomes high and low alternately according to the frequency of the signal. This triggers mono-stable timer U2 through. And the TR pin of 555timer goes low then pin3 of timer becomes high. When pin3 is high then buzzer will...
Timers TIM3 and TIM4 are 16-bit versions of TIM2/TIM5. Timers TIM9, TIM10 and on are stripped-down versions of timer TIM4, and so on. A simplified block diagram for timer TIM2 is given in Fig. 9.2 (reference manual RM0090, Figure 134, page 577). ...
