- What is the channel capacity if you have 16 signal levels and the bandwidth is 8 KHz?
- What is the wavelength if the speed/velocity of the wave is 100 m/s and frequency is 200Hz ?
- What is the frequency of the period is 4 s ?
Homework Answers
Question 1
Channel capacity is calculated in bit rates. The formula for a noiseless channel is
Capacity = 2 * Bandwidth * log2 L
Kilo = 1000
L means the number of signal levels
Capacity = 2 * 8000 * log2 16 = 2 * 8000 * 4 = 64000 bps
Question 2
Speed = Wavelength x Wave Frequency
100 m/s = wavelength x 200 Hz
wavelength = 0.5 meters
Question 3
Frequency = 1/T Where T is period
Frequency = 1/4s = 0.25 Hz
1/s gives Hz unit and 1/4=0.25
