Imagine that six binary bits are to be transmitted to a place where electrical noise is an issue and you would like to perform a parity generation/check to make sure that the received product is error free. Assuming that only a single bit error can occur and an odd parity generator/checker: a. Design the parity generator circuit b. Show how the six binary bits will be connected to the...

In most circuits the resistance of wires is negligible. Over long distances, however, it can become significant. Imagine a 160 km long cable from the power plant. It is 0.9 cm diameter and made of aluminum, with resistivity of 2.65x10m. It carries current to light your 60 W light bulb which is connected to your 120 V outlet. a) What is the resistance of the cable from your power plant? R- b) How much current goes through your light bulb?...

In last week's written HW you used a voltage to generate motion
in a sliding metal rail
that slid along two wires on the ground. This week you'll
consider the opposite case, moving
the rail to generate a voltage and power a lightbulb. Again the
rail is free to move along the
wires without any friction. The fixed wires are now 1 m apart
and at t = 0 the rail is 2 m
from the bulb.
