What controls the output frequency of an oscillator using the 555 timer?
What will be an ideal response?
The output frequency of an oscillator using the 555 timer is determined by the values of capacitor C1 and resistors R1 and R2. The 555 timer will operate at almost any frequency desired. It is used in many industrial electronic circuits that require the use of a square wave oscillator.

Answer the following statement true (T) or false (F)
Joyce and Vincent, both engineers, got married and raised three children over an 18-year period and the first one is now ready for college. There have been good and bad years financially; Joyce quit work for some years to raise small children, Vincent lost his job in year 10 and had to start a new career. The two have summarized the basic information from their tax returns for the 18 years. They wonder what percentage of their gross income has gone to federal taxes over the years. Apply the tax rate in the latest IRS Publication 17 (www.irs.gov) for married, filing jointly to calculate their taxes each year using a spreadsheet and plot the percentage of GI.
Assume exemptions are deducted as follows for each person (adult or child): years 1 to 8, $3500; years 9 to 14, $4000; years 15 to 18, $4500. (All monetary amounts are in $1000 units.)
