Chapter 16:dsp Flashcards
What does DSP make possible?
DSP makes possible adaptive filters software updates and functions impossible with analog.
What effects does DSP eliminate?
DSP eliminates the affective component tolerance temperature and component aging?
What is a 200 Hz signal produced by sampling a 4000 Hz signal called?
A signal produced by sampling another signal is called an alias.
What frequency do anti-alias filters have?
Anti-alias filters have a low pass frequency.
What is another name for an analog signal?
Another name for an analog signal is a continuous signal.
What is another name for a digital signal.
Digital signals are also referred to as discrete signals.
What is the basic frequency response of a moving average filter?
The basic frequency response of a moving average filter is low pass.
What is the term for the coefficients of a moving average filter?
The coefficients of a moving average filter are also called taps.
What is the formal name for the multiply and accumulate procedure?
The formal name for multiply and accumulate is convolution.
How many time delays are there in a 17 tap filter?
There are 16 time delays in a 17 tap Filter.
What does the Fourier transform convert?
The Fourier transform can convert from the time domain to the frequency domain?
What domain does an Oscilloscope display?
And Ocilloscope displays the time domain?
What domain does a spectrum analyzer display?
A spectrum analyzer displays the frequency domain.
What is Gibb’s phenomenon?
Synthesis of functions with discontinuities causes distortions called Gibbs phenomenon.
What are the core ideas of an inverse Fourier transform?
The core ideas:signals can be decomposed into sinusoids. signals can be decomposed into a series of single frequencies.signals can be synthesized using a series of sinusoids.
