ko ổn

[Khac-Hai]

public class DiscreteSignal implements Signal {

@Override
public void processSignal() {
    // Implementation of discrete signal processing
    System.out.println("Processing discrete signal.");
}

// Additional methods and attributes specific to DiscreteSignal
public double calculateDiscreteValue(int n, int k) {
    if (n == k) {
        return 1.0; // δ(n - k) = 1 when n = k
    } else {
        return 0.0; // δ(n - k) = 0 otherwise
    }
}

} dùng code này
