Consider both QPSK and 16-QAM constellations and answer the following questions:
1. Assign a Grey bit mapping to the symbols for both constellations.
2. Compute the symbol error probability for both constellations in terms of the Gaussian error integral Q(x).
3. Compute the bit error probability for both constellations in terms of the Gaussian error integral.

Consider an InGaAs APD with excess noise x=0.7, M=10 where M is the multiplication factor. The unmultiplied dark current is 10 nA and bandwidth is 700 MHz. What is the avalanche photodiode noise current per square root of bandwidth
A calibrated RTD with ALPHA = 0.0041/°C, R = 306.5 Ohms at 20°C, and PD = 30 mW/°C will be used to measure a critical reaction temperature. Temperature must be measured between 50° and 100°C with a resolution of at least 0.1°C.
The magnetic tape recorder uses linear analog to digital encoding. Telephone systems use non linear analog to digital conversion. Explain the difference.
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M.
