Q1. An FM transmitter has the block diagram shown in Figure Q1. The audio frequency response is constant over the 20 Hz to 20 kHz audio band. The FM output signal is to have a carrier frequency of 90.7 MHz and a peak deviation of 75 kHz. (b) Calculate the frequency fo of the oscillator. FM exciter fc = 5.00 MHz 1998* Oscillator fo= ?

I have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds. What's the procedure to connect the components? What's the Arduino code (C++) for this project?
