Intersymbol Interference

By Sweetwater on February 21, 2005

Also known as ISI. In digital audio or video a clock serves as a timing reference for a system. Everything in digital audio and video is related to a clock. There are specified numbers of operations per period of time and they all must be carried out at a consistent speed in order for the device to work properly. The ‘mechanism’ of a digital clock is a pulse. Intersymbol interference (ISI) is reduction or smearing in the distinction of a pulse caused by overlapping energy from neighboring pulses. ISI may result in data dependent deterministic jitter.

If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
