Consider an AM broadcast station that transmits modulating frequencies up to 10kHz. If it transmits a frequency of 1000 kHz. Find its maximum and minimum upper and lower sidebands frequencies and also the total bandwidth? Correct Answer 1010 KHz, 990 KHz, 20000 Hz

Maximum Frequency, fm = (1000 + 10) KHz = 1010 KHz. Minimum Frequency, fl = (1000 – 10) KHz = 990 KHz and, Bandwidth = 2 * Modulating frequency = Maximum Frequency – Minimum Frequency = (1010 – 990) KHz = 20000 Hz.

There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
