define a matlab question and solve with matlab codes (rlc circuts)

You are given the task of combining both analog phase modulation(PM) and analog frequency modulation(FM) transmitters . Describe the procedure to combine these transmitters into a single one such a way that your new transmitters operates only in one of the modes (either analog PM or FM) at a time based on the arbitrary choice of transmitter side user and the transmitter side user could change the mode anytime he/she wants during the operation.

Generate a transmitted dada sequence for “101010” using Hamming code? If an error occurs in the third bit, the received data is 101011”, how would Hamming technique fix it?

A 120+m -V , 2400+n-rpm shunt DC motor has a armature resistance 0.4+0.1*m ohm and a shunt field resistance of 160+m Ohm . The motor operates at its rated speed with full load which takes 15+m Amp.

1. We want to design a discrete-time bandpass filter that samples and processes analog signals. The frequency response is 0 at 0 Hz and 500 Hz, and resonant occurs at 125 Hz. The sampling interval T= 1 msec. Find the transfer function H[z] of these filters and mark the poles and zeros on the complex plane.

Design a microcomputer system using a uP 8086 10 Mhz. This system must have a Coprocessor 8087, a parallel connector, a serial connector, ADC and DAC connector for data conversion, a 16 byte seven segment display, a 64-key matrix keyboard, a USB connector thru a DMA for high speed data transfer. A special connector to connect a printer. The system must have an interrupt controller to handle all the I/O interface. The main memory size will be 1 Mbyte.

Show all the diagrams needed to construct your design including all the I/O interface and devices connected, show a memory map and the type of memory you will need for you design including the configuration and decoding system. You must include the programming needed for set up the complete system. Use pseudo code for each driver and program each of the interface needed.

Briefly explain the working principles and the main advantages of pulsed and frequency hopping GPR types. What is the advantage of using broadband GPR? What parameter of the GPR bandwidth pulse signal is set? What is the advantage and disadvantage of increasing PRF?

how the attenuation affects the maximum fiber length of communication links. Also explain how the index of refraction parameters or the type of fiber (step vs graded) affect the maximum data rate. Finally explain is the data rate a direct function of the intrinsic fiber attenuation?

Research and find an application of either a shift register or a counter. Counter systems are all around you everyday. For purposes of this discussion, you can include mechanical counters. These types of counters still exist. Although they are being replaced by digital electronic counters. Please don't use traffic lights as an example.
