transistors - Cant understand an ab amplifier diagram


enter image description here


I been trying to figure out this diagram, and Can't understand what happens from the beginning of the input , how the voltage changes in a way that "shuts off" one transistor. Also cant understand the direction in which it goes in the input signal .


Does the voltage goes off completely on one transistor at a time whle there is a signal ?


How does the signal works in the preamplifier transistor?



What path does the current takes when the signal changes in the input?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
