Inductor is the main cause which deviates the center frequency regardless of message
signal. Due to the reason use of inductor in FM Modulator is critical. Similarly, in case of
IC modulators inductor induces a process called gyration. An alternate approach to solve
the above mentioned problem is the use of Wien Bridge Oscillator.
Design a FM modulator with the help of Wien Bridge Oscillator for pure sinusoidal
output. Choose minimum number of passive components to minimize harmonics. The
output of modulator would be in Narrow Band FM.

In a flow control loop in a process for which you are specifying a flow sensor, it is undesirable to insert any sensing device into the actual flow because of interference with the flow. Because of the corrosive nature and high pressure and temperature of the flow, only stainless steel pipes can be used anywhere in the system. The liquid is non-conductive. Recommend a flow sensor, explaining its operating principle.

Consider a 12-bit ADC with an analog input voltage range of 0 to 3 volts.

a) Compute the ADC precision, ADC ranges for input and output, and ADC resolution.

b) What is the binary value computed by the ADC for an analog input voltage of 1.0 volt?

c) Write an ADC0_In function in C that uses busy-wait synchronization to sample the ADC. The function reads the ADC output, and returns the 12-bit binary number. Assume the ADC has already been initialized to use sequencer 3 with a software trigger and channel 1. See supplement pages for ADC registers.

Design the pyramidal horn antenna which operates at WLAN point to point frequency. The horn antenna must have directivity of 22 and HPBW of 30 degree in E plane. Then, determine the power gain (in dB) and the HPBW in H plane of this antenna. Please give your opinion about this antenna.

Design by multisim software a square, triangular and sine wave generator. Prepare the design calculations, gain and feedback frequencies of each of the circuits to implement.

1) In a single design, implement 3 wave generators by means of AOP (Operational Amplifiers): wave square, triangle wave, sine wave.

2) The wave generating equipment has to be activated by means of an external AC source, that being activated by a switch, allows the activation of the system (IMPORTANT)

3) Prepare the calculations of each case, which support the output signal obtained by use any of the generators.

Screenshot of simulated multisim circuits is required. and the calculations on a sheet

Design a circuit that takes two strings of binary digits and outputs 1 (True) if the strings “partially” match, and 0 otherwise. To keep this manageable assume the two strings are three bits long, that is a1a2a3 and b1b2b3 where each ai or bi is a one or a zero. The strings are a perfect match if for all i, ai = bi;. The strings are a partial match if at most one i, ai is not equal to bi. A perfect match can be considered a partial match.
