(a) The operation of the watchdog timer is controlled by the 16-bit register WDTCTL. It is guarded against accidental writes by requiring the password WDTPW = 0x5A in the upper byte. What would happen if a value with an incorrect password is written to WDTCTL? What value would return after reading the upper byte of WDTCTL?
(b) The watchdog timer is clocked from either SMCLK (if WDTSSEL = 0), or ACLK (if WDTSSEL = 1). The WDTISx bits of the register WDTCTL select the watchdog timer interval as following multiples of the period of the chosen clock:00: 3276801: 819210: 51211: 64Assume that fSMCLK = 2 MHz, and fACLK = 32,768 Hz. Fill in the table with the watchdog timer intervals.

(c) What are the largest and smallest achievable watchdog timer intervals, assuming that fSMCLK = 2 MHz, and fACLK = 32,768 Hz?
A 100Ω load needs 10mA to operate correctly. Design a practical power source to provide the needed current. The smallest source resistance you can practically design for is 50Ω, but you can add any other series resistance if you need to.
1-If the AB current in a Y-connected load has an angle of -14°, what is the angle of the a-phase current. (0 decimals in degrees) 2-If the current of the a-phase in a Y-connected load has an angle of -73°
Design a CMOS Differential pair amplifier with a low frequency gain of at least 30dB, while driving a resistive load 50-ohm. The available circuit components are NMOS transistor, PMOS transistor, resistors, capacitors and inductors.
The speech quality for a particular mobile communication system is just acceptable when the received power at the terminals of the mobile receiver is -104 dBm. Find the maximum acceptable propagation loss for the system, given that the transmit po..
A 26 resistor is connected across a 65 V battery. How much energy is used by the resistor in 5 min
a. Express the transfer function in descending powers of s with the coefficients of the highest power of s unity in both the numerator and denominator. b. Determine where the poles and zeroes of the transfer function are located.
A given signal f(t) is multiplied by this periodic signal. Determine an expression describing the spectrum and the time waveform of the resulting amplitude-modulated signal if all componets except those centered at + Wc
What is the uncertainty in position of an electron of an atom if there is ± 2.0 x 10^7 m·sec-1 uncertainty in its velocity Use the reduced Planck's constant and electron mass = 9.109 x 10-31 kg.
Design a counter to count even numbers between 0 and 15. Therefore states will be 0 -> 2 -> 4 -> 6 -> 8 -> 10 -> 12 -> 14 -> 0. If any unused state is encountered bewteen 0 and 7, then the counter should go back to initial state 0.
The exponential Fourier series coecients for a signal x(t) are: ak= { 1.57 when k=0, 0 when k is even and k doesnt equal 0, ((-1)(k-1)/2)/k when k is odd} Determine the following: (a) Plot the spectrum of the Fourier series.
For a circuit we would like to implement, there are two control signals: x and y. If xy = 01, an 8-bit value R is incremented by 1 and control goes to a second state. If xy = 10, R is cleared to zero and control goes from the initial state to a th..
