What is pps signal?
A pps signal stands for pulse per second. It is electric and repeats one every second. Pulse per second is mostly involved in health care; for example, nursing.
What is the second step in the pulse code modulation process?

Difference between discrete and digital signal?
THE TERM CONTINUOUS SIGNAL AND DISCRETE SIGNAL CLASSIFY THE SIGNALS ALONG THE TIME (i.e. horizontal axis) where as THE TERM ANALOG AND DIGITAL SIGNAL CLASSIFY THE SIGNAL ALONG THE AMPLITUDE (i.e vertical axis) we often confuse our-self with continuous time and analog signals. An analog signal is a signal which can take any amplitude in continuous range that is signal amplitude can take infinite values on the other hand a digital signal is one whose amplitude can take only finite numbers of values
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What is the main advantage of digital transmission over analog transmission?
digital signal is less susceptible to signal degradation due to the nature of it's transmission signal which is either on or off and therefore less errors occur as analog is prone to signal degradation and loss that is why digital tv is crisp and clear and analog is somewhat blurry in comparison, also with higher bandwidth achievable by digital transmission more data is able to be transmitted.
Is pulse wave an analog or digital signal?
Yes, it is

A digital signal composed of a pulse of positive voltage represents a what?
A pulse is just a pulse. Its meaning depends on context and the design of the system.
What digit represents a digital signal composed of a pulse of positive voltage?
A pulse is just a pulse. Its meaning depends on context and the design of the system.
Is a bit is every pulse in a digital signal?
A bit is an on or off; (high or a low ; one or zero, depending on the logic.) A string of bits might be seen as "one pulse", but it is the bit Rate which must be considered.
Pulse Position modulation is digital or not?
Pulse position modulation can be analog or digital, it depends on the signal and/or the modulator used to obtain the modulation. If an analog signal is applied at the input of the modulator, the position of the pulse can assume an infinity of different timing states (the signal vary continuously) and hence an analog modulation is realised in PPM. On the contrary if the signal is digitized previously in a series of discrete states, the pulse at the output will have discrete timing interval (not continuosly). Then a digital modulation is obtained. If the signal is analog, but the modulator is digital, we will have again a number of finite state in output timing, and the PPM will be digital. To be noted that, if the number of steps in the digital modulator, is higher then the dinamic range required, the performance of the digital and analog PPM will be exactly the same. Cecking the front of the pulse of PPM with a digital oscilloscope capable of jitter measurament, we will see immediately if the position of the pulses will be continuosly variable or a number of discrete steps will be presented. We can then consider analog and digital PPM physically different.
What does digital data mean?
A digital signal is a physical signal that is a representation of a sequence of discrete values (a quantified discrete-time signal), for example of an arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal. The term digital signal can refer to either of the following:any continuous-time waveform signal used in digital communication, representing a bit stream or other sequence of discrete valuesa pulse train signal that switches between a discrete number of voltage levels or levels of light intensity, also known as a line coded signal or baseband transmission, for example a signal found in digital electronics or in serial communications, or a pulse code modulation (PCM) representation of a digitized analog signal.A signal that is generated by means of a digital modulation method (digital passband transmission), to be transferred between modems, is in the first case considered as a digital signal, and in the second case as converted to an analog signal.
What is the pulse width duration of a 500-hz digital signal if the duty cycle is 20 percent?
4ms
What is pwm?
PWM stands for Pulse Width Modulation. It is a technique used to encode a message into a pulsing signal by varying the width of the pulse relative to a fixed time frame. PWM is commonly used in controlling the speed of motors, regulating power to LEDs, and generating analog voltage levels from digital signals.
What is pps signal?
A pps signal stands for pulse per second. It is electric and repeats one every second. Pulse per second is mostly involved in health care; for example, nursing.
What is the two level digital puse amplitude modulation?
In Pulse Amplitude Modulation, amplitude of pulse varies with signal. Theoretically in analog modulation there infinite levels of amplitudes or continuous amplitude. Two level PAM is digital modulation where only 2 number of levels are there. Thus signal is quantized to two discrete levels.
What is the second step in the pulse code modulation process?
digital converter extracts samples of analog signal from input siganl digital converter quantizes analog sample and assignes a binary numbervalue to it digital coanverter encodes a quantized analog signal to transmit it across a digital network
