01
Direct-conversion (zero-IF) architecture chosen for simplicity
02
Inclusion of LNA for signal amplification
03
Local oscillator drives mixer for frequency translation
04
Low-pass filter removes high-frequency components after mixing
05
ADC digitizes the baseband signal for DSP processing
Useful in communications systems design, SDR education, or illustrating receiver architectures.
