3. Calculate the wavelength of the signal of sin(200kπt+π/3) with the propagation speed of 3000m/s
4. Plot the frequency component of signal 4sin(200πt+π/3) + sin(10πt-π)
What is the bandwidth of this signal?
5. What is the bit rate for the given digital signal in Figure
6. What is the channel capacity for a teleprinter channel with a 300-Hz bandwidth and a signal-to-noise ratio of 3 dB?
Shannon's equation: C = B log2 (1 + SNR), SNRdb=10 log10 (SNR)
7. A digital signaling system is required to operate at 14400 bps.
If a signal element encodes a 4-bit word (M=24=16), what is the minimum required bandwidth of the channel? Using Nyquist's equation: C = 2B log2M.

Find the image distances from the rear surface of the lens
: The refractive index of the lens at these two wavelengths is 1.522376 for the blue and 1.514322 for the red. Because the refractive index is not the same for both wavelengths, there will be two images. Find the image distances from the rear surfac..
