Pulse Width Modulation
Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) or Pulse Time Modulation (PTM) is an analog modulating scheme in which the duration or width or time of the pulse carrier varies proportional to the…
Types of Pulse Amplitude Modulation
There are two major types of PAMs: Single polarity PAM: Here, an appropriate fixed DC bias is integrated with the signal to assure that all pulses are positive.Double polarity PAM: Here, the…
Pulse Amplitude Modulation
Pulse amplitude modulation is defined as the data transmission by altering the amplitudes (power levels or voltage) of every pulse in a regular time sequence of electromagnetic pulses. The possible…
Sampling Theorem for Low Pass Signals
The low pass signals having the low range frequency and whenever this type of low-frequency signals need to convert to discrete then the sampling frequency should be double than these…
Nyquist Sampling Theorem
In the sampling process, while converting the analog signal to a discrete version, the chosen sampling signal is the most important factor. And what are the reasons to get distortions…
What is the Sampling Theorem?
A signal has three properties like voltage or amplitude, frequency, phase. The signals are represented only in an analog form where the digital form of technology is not available. Analog signals are continuous in…
Aliasing, Anti-aliasing
In electronics it’s not about changing a name, but it is about the very gross distortions that can happen in sampled data signal processing. To keep it simple, consider an…
Sampling
Sampling is defined as, “The process of measuring the instantaneous values of continuous-time signal in a discrete form.” Sample is a piece of data taken from the whole data which is continuous…
Digital Communication System
The transmission of information from the sender to the recipient through some medium is called as communication. Communication enables us to know what is happening around us. It helps us…
Network Layer Protocols
Every computer in a network has an IP address by which it can be uniquely identified and addressed. An IP address is Layer-3 (Network Layer) logical address. This address may…
