Which pulse modulation scheme is used as an intermediate step in the creation of PCM?
The pulse amplitude modulation (PAM) scheme is used as an intermediate step in the creation of pulse code modulation (PCM). In PAM, the amplitude of discrete pulses represents the sampled values of the analog signal. These amplitude levels are then quantized and encoded into a binary format to produce the final PCM signal. This process enables the efficient digital representation of analog information for transmission and storage.
What are disadvantages of using excess 3 code?
Excess-3 code has several disadvantages, including its complexity in arithmetic operations, as it requires conversion to binary-coded decimal (BCD) for calculations, which can slow down processing. Additionally, it consumes more memory than simpler encoding schemes, as each digit is represented by four bits instead of the more compact binary representation. Furthermore, the coding scheme can complicate the design of digital circuits, leading to increased costs and potential for errors in implementation.
What is the need of digital modulation scheme?
The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a filter limits the frequency range to between 300 and 3400 Hz) or a limited radio frequency band.
Distinguish between logical data independence and physical data independence?
logical data : refer to the immunity of the external scheme towards changes in the conceptual scheme.physical data: refer to the immunity of the conceptual scheme towards changes in the internal scheme.
How do you make a car rental scheme using javascript?
You need JavaScript and HTML to make car rental scheme. You might also need a middleware.

Which analog modulation scheme requires minimum transmitted power and minimum channel bandwidth?
ssb modulation scheme
What is letter addressing scheme?
A letter addressing scheme has to do with a TCP/IP protocol. Addresses are determined by both decimal and binary counting.

How do you represent Real Numbers in Binary Form ie In Computers Main Memory First express in mantissa and exponent form In a sixteen bit scheme first 10 bits are reserved for mantissa other six bi?
It depends on the standard you are using. For further information read more about number representation standards.
What is the base of a character?
In computer science, the "base" of a character typically refers to its character encoding, which defines a mapping between characters and numeric values (often in binary form) for representation in digital systems. The base can vary depending on the encoding scheme used, such as ASCII, Unicode, or UTF-8, determining how characters are stored and interpreted by computers.
What are the definitions of PLANNING?
Nouns- 1.) the act or process of making plans. 2.) a scheme or method of acting, doing, making, proceeding, etc. 3.) a design or scheme of arrangement. 4.) a specific project. 5.) a representation. Verbs- 6.) to arrange a method or scheme 7.) to draw/make a diagram of a layout
Define constellation diagram and its role in analog transmission?
A constellation diagram is a representation of a signal modulated by a digital modulation scheme such as quadrature amplitude modulation or phase-shift keying. It displays the signal as a two-dimensional scatter diagram in the complex plane at symbol sampling instants. In a more abstract sense, it represents the possible symbols that may be selected by a given modulation scheme as points in the complex plane. Measured constellation diagrams can be used to recognize the type of interference and distortion in a signal.By: ISRAFIL CSE

Define binary coding scheme in computer system?
A binary coding scheme is a method of representing data using only two symbols: 0 and 1. In computer systems, these symbols are used to represent digital information at the lowest level, with each digit called a "bit" (binary digit). By combining bits in patterns, binary coding enables computers to store, process, and transmit data.
