pulse rate modulation

The modulating signal is sampled at the basic rate, usually where f m is the maximum value. The amplitude of the modulation determines the amplitude of the transmitted pulse. The band-width will be great for exact pulse waveform, but may be redu..

Pulse Modulation - In amplitude modulation and frequency modulation, the modulation was done by sinusoidal signals. In pulse modulation, short pulses may do the modulation of a radio-frequency carrier. The sim..

Pulse is defined as the wave of distension and recoiling felt in the radial artery due to the contraction of the left ventricle which force about 70-90 ml of blood into the already full aorta. It can be felt in the superficial arteries such as those in the wrist, neck, temples and ankles...

The timing or position of the pulse is varied around a fixed mean value and conforms to the signal amplitude at the time of sampling. A positive signal may set the pulse ahead, a negative signal will set the pulse behind the reference time. In reception, the puls..

The number of times the heart beats per minute is called heart rate. For a normal adult human it is about 72 times per minute. For infants, it is a higher figure. It also goes up during physical exercise. The contractions and relaxations that the heart chambers undergo are felt all along ..

ECG is a graphic display or recording of the electrical variations produced by heart muscle during a cardiac cycle. The activity of the heart create an electrical field which is conducted through the surrounding body tissues to the surface of the body. Two electrodes are placed on the surface of th..

Principles of Light Modulation - Let us consider the case of electromagnetic radiation in an ionised medium. Suppose we increase/decrease the amplitude of an electromagnetic wave passing through an ionised gas. These modulations of the electromagnetic wave could contain coded in..

The sample consists of pulse rate measurements of 30 workers placed at random into 3 different groups, which performed different work tasks. At α = 0.01, find the F test value and is there a significant difference in the mean pulse rate among the groups..

Pulse is defined as the wave of distension and recoiling felt in the radial artery due to the contraction of the left ventricle which force about 70-90 ml of blood into the already full aort..

Which of the following situations best represents the graph? => The pulse rate doubles with age. or The pulse rate decreases with age. or The pulse rate increases with age. or The pulse rate does not change with age...
