1) On your first job, you are taking over a project involving the phase-locked loop (PLL) system is shown in block diagram form at the top of the opposite page. The charge pump phase-frequency detector (CPPFD) has a maximum output current of Icp = 5μA for 2Π radians of phase difference. For the voltage controlled oscillator (VCO) in the system, the V-f measurements in the table were obtained.
a) Since the VCO voltage-to-frequency characteristic is nonlinear, the VCO tuning gain Kvco changes as a function of VCO control voltage VCTL. Estimate (accuracy ±10%) the minimum and maximum values of Ko over the voltage tuning range.

Design a two-levelcombinational logic circuit to implement theadditionof two 2-bit numbers. Donot use half adders or full adders as building blocks forthis circuit. Rather, follow the logic circuit design process discussed in class.
a.) Plot x[n] as a function of n and use the definition of the z - transform to find x[z]. b.) Use the z - transform of u[n] and properties of the z - transform to find x[z]. Verify that the expressions obtained above for x[z] are identical.

Develop the ow-graph for the FFT algorithm from the radix-2 FFT algorithm for the N = 9 case in which the input is in the bit-reversed order and the output is in normal order.
A speech signal with bandwidth B= 10 Khz is sampled at F2 = 20 KHz. Suppose that the signal is corrupted by four sinusoids with frequencies. F1 = 10,000 Hz ,F2 = 8889 Hz, F3 = 7778 Hz , F4 = 6667 Hz
To understand this, imagine we paint one of the blades of an airplane propeller so that we can identify it from the other blades. We will then turn the propeller at 33 rotations per second, in a clockwise direction.
The temperature of steam at the inlets of both turbines is 500°C, and the enthalpy of steam is 3185 kJ/kg at the exit of the high-pressure turbine, and 2247 kJ/kg at the exit of the low-pressure turbine. Disregarding the pump work, determine the w..
