1. What is the new ideal interpolation formula described after few problems with previous one?

2. What is the quantity ax(n-1) is called?

3. There is no requirement to process the various signals at different rates commensurate with the corresponding bandwidths of the signals.

4. D/A conversion is usually performed by combining a D/A converter with a sample-and-hold (S/H ) and followed by a low pass (smoothing) filter.

5. We need not relate the spectrum of y(m) to spectrum of x(n) to obtain frequency response characteristic of y(m).

6. What is the expression for low pass signal component uc(t) that can be expressed in terms of samples of the bandpass signal?

7. The sequence \(\bar{v}(n)\) can be obtained by multiplying v(n) with a signal p(n) of period D.

8. The simplest form of differential predictive quantization is called?

9. In a D/A converter, the usual way to solve the glitch is to use deglitcher. How is the Deglitcher designed?

10. In the equation x(t) = Re\([x_l (t) e^{j2πF_c t}]\), What is the lowpass signal xl (t) is usually called the ___ of the real signal x(t).
