Define some Applications of Digital Counters?
Digital counters are extremely useful in many applications. They can be effortlessly found in digital clocks and parallel-to-serial data conversion (multiplexing). A group of bits appearing concurrently on parallel lines is called parallel data and a group of bits appearing on a single line in a time sequence is called as serial data.
Parallel-to-serial conversion is usually accomplished by the use of a counter to provide a binary sequence for the data-select inputs of a multiplexer as illustrated in the circuit.
Thus The Q outputs of the modulus-8 counter are connected to the data-select inputs of an eight-bit multiplexer and the first byte (eight-bit group) of parallel data is applied to the multiplexer inputs. As the counter goes throughout a binary sequence from 0 to 7 each bit beginning with D0 is a sequentially selected and passed through the multiplexer to the output line. After the eight clock pulses the data byte has been converted to a serial format and sent out on the transmission line then the counter recycles back to 0 and converts another parallel byte sequentially again by the same process.
Error-Rate Control, Output-Rate Control, and Integral-Error (Reset) Control Let us consider a typical second-order servomechanism(containing two energy-storing elements) whose
Q. Consider the synchronous counter shown in Figure of the text. (a) Draw its timing diagram. (b) Show the implementation of the same synchronous counter using D flip-flops.
Q. What do you mean by Companding? In order to lower the crest factor of a waveform, so as to produce better performance, a process known as companding is used. It works like a
1) Assume that we are given the continuous-time signal xa (t) = xa1 (t) + xa2 (t) + xa3 (t), where, xa1 (t) = 2 + cos3 (2pf1 t + p 3 ) + 2 cos(2pf2 t), xa2 (t) = 2 cos(2pf3 t)
