Charge time is independent of signal amplitude because the charging process primarily depends on the capacitance and resistance in the circuit rather than the voltage level of the signal. In a capacitor, the time constant, defined as the product of resistance (R) and capacitance (C), dictates how quickly it charges or discharges, regardless of the input voltage. Therefore, as long as the signal is above a certain threshold, the rate of charge remains consistent, making charge time invariant to amplitude changes.

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
How do you draw graph of modulation waves?
To draw the graph of modulation waves, first identify the carrier wave and the modulating signal. For amplitude modulation (AM), plot the carrier wave's amplitude varying based on the modulating signal's amplitude; the resulting waveform will show peaks that correspond to the modulating signal. For frequency modulation (FM), depict the carrier wave's frequency changing based on the modulating signal's amplitude, resulting in a waveform with varying spacing between peaks. Use appropriate scales for time and amplitude to accurately represent the modulation effects.
What is the input and output of waveform?
In waveform analysis, the input typically refers to the electrical signal or data that represents a physical phenomenon, such as sound, light, or voltage, which is processed over time. The output is the graphical representation of that signal, shown as a waveform, illustrating variations in amplitude over time. This output can be used to analyze the characteristics of the input signal, such as frequency, amplitude, and phase.
What is an analog signal and a digital signal?
An analog signal is one which is continuous in time as well as continuous in amplitude . Example : sine wave, cosine wave. An Digital signal is one which is continuous in discrete in time. Example : square waves.
What are the properties of signals?
Signals possess several key properties, including amplitude, frequency, phase, and duration. Amplitude refers to the strength or intensity of the signal, while frequency indicates how often a signal oscillates over time. Phase describes the position of the waveform in time, and duration refers to how long the signal lasts. Additionally, signals can be classified as analog or digital, depending on whether they represent continuous or discrete values.
What are the characteristics of a periodical?
A periodic signal has two major characteristics: frequency and amplitude. Frequency is the number of times the periodic signal occurs in a set time, and the amplitude refers to how strong the signal is.
If amplitude decreases what happens to frequency?
If the amplitude decreases, the frequency remains unchanged. Amplitude refers to the magnitude of the signal, while frequency refers to the number of oscillations per unit of time. Changing the amplitude does not affect the frequency of the signal.

What is the amplitude of am waves?
The amplitude is the amount of power the transmitter is putting out depending the signal being fed into it from the source. It varies constantly with the signal. It is called amplitude modulation. Modulation of over %100 can cause the transmitter to send harmonics called band splatter.
What is instantaneous amplitude?
Instantaneous amplitude is the magnitude or strength of a signal at any specific point in time. It measures the maximum distance of a wave from its baseline or center point at a particular moment in time. In telecommunications and signal processing, instantaneous amplitude is important for modulating signals and analyzing waveforms.

Can low frequency have a large amplitude?
Yes, low frequency signals can have large amplitudes. Amplitude refers to the strength or intensity of a signal, while frequency refers to the number of cycles of the signal that occur in a given time period. So, a low frequency signal can still have a high amplitude.
What is mean by the envelope of an AM waveform and inummerate?
The envelope of an Amplitude Modulated (AM) waveform represents the outline or contour that defines the varying amplitude of the carrier signal over time, reflecting the information signal's modulation. It typically appears as a smooth curve that follows the peaks of the modulated wave, indicating the instantaneous amplitude of the signal. The envelope can be visualized as the maximum and minimum amplitude levels of the AM wave, and it is crucial for demodulation in communication systems.
