A 5 MHz ultrasound pulse is transmitted in pulsed Doppler blood flow measurement. Velocity of sound in blood is 1500 m/s. A rectangular pulse train used for transmission and receiving with a duty cycle of 25% and pulse frequency of 10 kHz. a. a. What is the 'on' period of the rectangular pulse in seconds? b. What is the period of the ultrasound wave that is transmitted in seconds? c. How many cycles of the ultrasound are transmitted during the ‘on' period? d. What is the duration of the ‘offperiod of the rectangular pulse? e. If the reflected wave has a frequency of 10.4MHz, what is the velocity of the blood?
