2. An ultrasound imaging system is equipped with a transducer, which operates at 10 MHz and has a diameter of 0.5 cm. The imaging system is tested in a medium having a speed of sound of 1560 m/s. The amplitude attenuation factor (ua) of the medium is 0.04 cm ¹MHz¹. It is aimed at imaging objects up to a range of 10 cm using the system. a) Compute the maximum loss in dB of the ultrasound waves received at the transducer. b) Using the simple model for the beam pattern, determine if the 10 cm depth is in the near field or far field for the transducer. c) What is the maximum pulse repetition rate for the system? d) What is the maximum frame rate if 128 A-lines are required for an image? e) What will happen to the B-mode image if the speed of sound in the medium is non- uniform, but we still use a uniform speed assumption?

Single Sideband Modulator Using Phasing Method
A sinusoidal haseband signal with a frequency of 5kHz is transmitted using DSB-LC. The received signal is R = 10[1 +0.2 cos(2m5000r)] cos(2r10°r) Volts. The shown system is used as a receiver. The BPF is ideal and its center frequency is 1.002MHz and bandwidth 7kHz. The demodulator has input-output characteristics (V, = 4V/). The LPF is ideal with an adjustable cutoff frequency. Determine the output signal waveform of this system. You need to specify the cutoff frequency of the LPF to obtain the original message back at Y. R BPF Demodulator B (B-4A) LPF DC removal
