Why is a demodulator needed to recover the pulse waveform?
The received waveforms are in the pulse-shape form. And yet the demodulator needs to recover the pulse waveform.Reason: The arriving waveforms are not in the ideal pulse shapes.Filtering caused ISI and signals appear to be "smeared" and not ready for sampling and detection.Demodulator goal is to recover baseband pulse with best SNR and free of ISI.
Can wires pass threw a transformer?
No, wires cannot pass through a transformer in the sense of being directly connected or intact. A transformer operates on the principle of electromagnetic induction, where electrical energy is transferred between coils of wire (windings) through a magnetic core. Any wires must be connected to the transformer terminals and cannot physically pass through the core itself.
How to generate sawtooth waveform of 0 to 5V from square wave of 0 to 15V...?
You will need a regulator circuit that will change the shape of the pulse AND regulate the voltage to 5v.
What is unipolar waveform?
A unipolar waveform is a type of electrical signal where the voltage fluctuates between a zero reference point and a positive or negative peak, but does not oscillate around zero. This means that the waveform only exists above or below the zero line, typically remaining positive or negative throughout its cycle. Unipolar waveforms are commonly used in digital circuits and signal processing, where a clear distinction between two states is needed, such as in pulse-width modulation. Examples include certain types of pulse signals and power supply outputs.
What is the duty cycle for a periodic digital waveform which has a frequancy of10kHz and a pulse width of 66microsecond?
The duty cycle of a periodic digital waveform is calculated using the formula: Duty Cycle (%) = (Pulse Width / Period) × 100. The period (T) for a frequency of 10 kHz is 1 / 10,000 Hz = 0.0001 seconds or 100 microseconds. Therefore, the duty cycle is (66 microseconds / 100 microseconds) × 100 = 66%.

What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?
You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.
What do you mean by pulse width modulation?
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
Do pulse transformer is work on dc supply?

Why should we use pulse transformer rather than ordinary transformer?
Pulse transformers are designed to accurately reproduce signals with fast rise-times. They are not very good at reproducing normal sinusoidal AC signals. Pulse transformers are used to trigger SCR's, for instance, in motor controls and lamp dimmers. If you open up a photoflash unit, you will most likely see a small pulse transformer used to trigger the high-voltage pulse to the Xenon photoflash tube.
How do you take the derivative of a sawtooth waveform?
Consider that a sawtooth waveform is the summation of the infinite series of sine waves with amplitude equal to 1 over the multiplier of the frequency. Now you can take the derivative, or at least approximate it. You will find that the derivative of a sawtooth is a pulse, in the ideal case, a pulse with infinite amplitude and zero width.
What is a signal pulse transformer?
usually a small transformer ferrite rather than iron core for short pulses it is more for isolation than anything else trigger for scr or triac the previous question for a power pulse transformer these are in cars ignition transformers the newer cars generally have one on each cylinder the computer may feed may feed a signal pulse through the small transformer to isolate the computer from the big one. to an scr to discharge a capacitor thru the ignition transformer (cars use the terms condenser and coil)

What is the difference between Pam ppm and pwm in digital communication?
PAM-pulse Amplitude Modulation It encodes information in the amplitude of a sequence of signal pulses. PPM-Pulse Position modulation PWM-Pulse Width Modulation.It results in variation of average waveform.
Which type of transformer is used in mobile charger?
The transformer used in mobile is pulse transformer which operates at very high frequency pulsating DC in order to make charger energy efficient and light weight.
