DIGITAL RECEIVER BLOCK DIAGRAM 

The simplified workflow of the digital receiver is as follows:

1. The Radio Frequency (RF) input signal first enters the system and passes through two cascaded Low Noise Amplifiers (LNAs) for signal amplification while minimizing noise interference.

2. The amplified RF signal goes through a Band-Pass Filter (BPF) to filter out unwanted frequency components, retaining only the target RF band.

3. The filtered RF signal is sent to the Mixer, where it mixes with the Local Oscillator (LO) signal to downconvert to an Intermediate Frequency (IF) signal.

4. The resulting IF signal passes through another Band-Pass Filter (BPF) for further noise and interference suppression.

5. The filtered IF signal is converted from an analog signal to a digital signal by the Analog-to-Digital Converter (ADC).

6. Finally, the digital signal is subjected to Digital Signal Analysis to extract useful information.
