A RTL-SDR v4 was configured with MATLAB to perform the FM radio receiver experiment in Simulink. 

The Simulink block diagram consisted of the RTL-SDR Receiver, tuned to the FM signal frequency of 100.3 MHz with a tuner gain of 40 dB, to capture the FM signals from the 100.3 MHz band. 

The FIR Decimation block was then added to downsample the signal. 

Connected to the FIR Decimation block is the FM De-emphasis Filter, which corrects the FM de-emphasis applied during broadcast transmission. 

The Scope and Audio Output blocks were connected to visualize the frequency spectrum of the captured FM signal, observe the time-domain representation of both modulated and demodulated signals, and output the audio corresponding to the frequency.
