Transient is the most hyped, abused and trendy word in GS. A transient is a short-duration signal that represents a nonharmonic attack phase of a sound source. It contains a high degree of nonperiodic components and a higher magnitude of high frequencies than the harmonic content of that sound.
But like any estimate, it's based on some rounded numbers and rules of thumb. For example, this mortgage affordability calculator assumes that your monthly mortgage payment should be no more than 28% of your monthly income, to leave enough money for other expenses and investments you'll want to make.
What monthly payment can you afford? Most lenders recommend that borrowers spend no more than 28 percent of their monthly income on a mortgage payment. For instance, if you make $8,000 a month and owe $500 in monthly debt payments, you could get a 30-year mortgage of up to $380,000 with 5 percent interest. Your monthly payments, representing 28 percent of your income, would be $2,040.
