Assignment:
Frequency divider
Design a frequency divider circuit that will output three pulse frequencies: 25 kHz, 10kHz, and 2.5kHz. Assume that only a 150 kHz CMOS compatible signal is available for the divider input. Use the 74163 IC in Multisim. Simulate, construct, and test the frequency divider circuit. Use a frequency counter in Multisim to verify the proper output frequencies of your circuit design.
The gas tank on your car has a fuel-level sending unit that works like a potentiometer. A float moves up and down while the gasoline level, changing the variable resistor setting and producing a voltage proportional to the gas level. A full tank produces 12V, and an empty tank produces 0V. Design a Multisim circuit using an LM339 that turns on “Fuel Level” indicator lamp when the voltage level from the sending unit gets below 0.5V
