The line diagram is of a standard forward/reverse/stop pushbutton station for forwarding and reversing a motor. Included in the circuit are mechanical and auxiliary contact interlocking. Also included are a forward overtravel limit switch to stop the motor in forward and a reverse overtravel limit switch to stop the motor in reverse. Overload protection is common to both forward and reverse directions. Complete the wiring diagram based on the line diagram. Do not make any wire splices or additional terminal connections on the wiring diagram (notice how they make multiple connections in the power circuit). All connections must run from terminal screw to terminal screw

6.7 Consider a baseband binary PAM system that transmits at 3600 bps with a bit
error rate less than 10-4. The channel introduces no distortion, but attenuates the
signal by 20 dB and has a bandwidth of 2.4 kHz. The channel noise is AWGN with a
power spectral density of 10-14 watts per Hertz (W/Hz). Design the optimum
transmitting and receiving filters, and determine the required transmit power.
6.10 In a baseband digital transmission, the bandwidth is 4 kHz, and the bit rate
must be at least 38.4 kbps. Assuming M-ary signaling, determine the range
of acceptable values of M, and the resulting bit error rate.

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 Vec). Assume that the amplifier is to interface a source that expects a load of 50 2.

Plot the received signal constellation using a red o to represent when a logical 0 was sent and a blue * to represent a logical 1 was sent Question (1) Increase the Eb/No to 7 dB.
