28(b) An Ideal Low-pass Filter and Its Impulse Response The time-domain characteristic corresponding to H(f) is given by Ideal Reconstructor Let us consider an analog signal x(t) with a frequency spectrum X(f) that has been sampled at the rate of 1/T samples per second. The sampled signal x(n) will have a spectrum that consists of replica of X(f) shifted by integer multiples of fs. Assume that the spectrum X(f) is bandlimited and the sampling rate is sufficiently high so that its replica do not overlap.
We have discussed the sampling of a low-pass signal. The minimum sampling frequency is twice that of the bandwidth of the signal. If the signal to be sampled is a bandpass signal, we do not normally want to sample at twice the frequency of the highest frequency component of this signal since much of the lower frequency components are useless. This lead to the topic of bandpass sampling. Bandpass sampling is of particular interest to applications in carrier modulated communication systems. G. L.
Each bit of the binary code turns on or off a corresponding current source. The sum of all the currents available can be converted to a voltage for output or remain as is. Figure 2-32 shows such a current source multiplying DAC. The current sources are normally on and are grounded when not in use. Digital-to-Analog Converters Digital-to-analog converters (DACs) are the implementations of the reconstructors. Since DACs are much simpler than ADCs, they are correspondingly cheaper. A digital binary code is converted to an analog output which may be a current or voltage.
