Understanding Digital Radio and Modulation Techniques
1. Digital Radio and Transmission
Digital radio involves transmitting digitally modulated analog carriers between points in a communication system. This requires a physical facility between the transmitter and receiver.
2. Digital Radio Systems vs. Conventional Radio
In digital radio systems, the modulator input and output signals are digital pulses. This distinguishes them from conventional AM or FM radio, where the modulating signal is analog.

1. Kruskal’s Algorithm
Kruskal’s algorithm finds the minimum spanning tree (MST) of a weighted undirected graph. It iteratively adds the edge with the smallest weight to the MST, ensuring that adding the edge doesn’t create a cycle.

#define INF 999
#define MAX 100
int p[MAX], c[MAX][MAX], t[MAX][2];
int find(int v) {

v Computational Complexity: P, NP, NPC, NP-Hard, DP, Network Flow, Approximation, and LP
Dynamic Programming (DP): DP is a technique for solving problems by breaking them down into smaller overlapping subproblems and storing the solutions to these subproblems to avoid recomputing them. This can significantly improve the efficiency of algorithms, especially for problems with exponential time complexity. For example, the Fibonacci sequence can be computed in linear time using DP, whereas a naive recursive approach would take exponential time.
Example:
Consider the problem of finding the
