1. Determine the capacitance length of a PCB embedded stripline, assuming no fringing of the electrostatic field.2. Determine the capacitance/unit length of the same embedded stripline using field plotting software (Femlab).3. Compare the results of 1 and 2 above and account for any differences.4. Compare the microstrip line with the embedded stripline from the point of view of both signal integrity and EMC
The strip line, which is made from copper and embedded in FR4, is shown in Fig A1_1.
Figure A1_1 The Embedded Stripline
You are expected to decide the dimensions of signal return planes.You must also find the value of the relative permittivity of FR4, and decide your own model setup for the problem solution in Femlab.
You may research the stripline as you feel is appropriate.
Q. A 230-Vdc shuntmotor delivers 30 hp at the shaft at 1120 r/min. If the motor has an efficiency of 87% at this load, find: (a) The total input power. (b) The line current.
State the functions of a fuse. Fuse is a protective device that made of a thin wire or strip. This strip or wire is placed with the circuit this has to protect, therefore the
Define Short Lines? For short power lines (up to 50 miles; 80 km), the effects of the shunt capacitance and leakage resistance are negligible. Hence the line may be represente
what are the functions of interpolar winding and compensating winding?
Q. Show NPN Common Collector Amplifier? The common collector amplifier, often called an emitter follower since its output is taken from the emitter resistor, is useful as
Suppose that a video signal, having W = 5 MHz, is transmitted via FM with f = 20 MHz. For 1/100 ≤ B/fc ≤ 1/10, determine the bounds on the carrier frequency. Use WFM ∼ = 2( ω + 2W
Static Rotor Resistance Control Methods This method is used only for slip ring induction motor in SRIM 3- phase variable resistor can be inserted in the rotor circuit and
High Voltage Distribution System or HVDS Adoption of HVDS (High Voltage Distribution System) through converting existing LVDS to HVDS reduces the technical losses appreciably.
Q. A separately excited dc generator with an armature-circuit resistance Ra is operating at a terminal voltage Vt, while delivering an armature current Ia, and has a constant loss
Explain RS232C Standard. RS232C: 1. Standard described for asynchronous communications where there is given timing among data bits and no fixed timing among the characters
