(1) A baseband PAM communication channel bandwidth is 100 KHz and has a noise power spectral density
of 10^-9 W/Hz. The channel loss between the transmitter and receiver is 25dB. The application requires a
bit rate of 500 Kbps and BER of less than 10^-5. The system uses raised cosine pulses with a roll-off factor
of 0.25. Determine the minimum transmit power required.
(2) Continuing problem 1. Everything for the previous problem stays the same BUT the best Power
Amplifier you can afford has a maximum output power of 10 Watts. What will be estimated BER for the
system?
Explain magnetic hysteresis and give examples of some calculations

- Assume a JFET device with VGS(0) = -1.3 and ipss = 20 mA. Design a self-biased (Fig. 2) JFET common-source amplifier with the gain of -2 and a DC biasing that allows the largest swing in ip. Note that you can choose Vcc to arrive at a desired RD to meet the gain requirement. Since you are designing for a given gain, you may have to check to see if JFET is biased correctly. (Hint: First find Rs for correct VGs and then use the gain to compute RD. Finally, use RD and Rs to determine Vcc). Assume that the amplifier is to interface a source that expects a load of 50 . Also, assume that the amplifier circuit is AC coupled at both ends with 3 dB corner frequency of 15 kHz. Rearrange the circuit in step 1 to implement a common-drain amplifier. Do note that the output capacitor (C2) must be redesigned as the output impedance of common-drain is different from that of common-source amplifier. What is the actual gain?
