What are the hardware elements in the embedded systems?
Hardware Elements in the Embedded Systems are as follows:
(i) Power Source
(ii) Clock Oscillator Circuit and Clocking Units
1. Suitable clock oscillator circuit
2. Real Time Clock (as System Clock)and Timers driving hardware and software
(iii) Reset Circuit
1. Reset onto Power-up
2. Internal and External Reset circuit
3. Reset onto Timeout of Watchdog timer
(iv) Memory
(v) Interrupts Handler
Interrupt Handling tool for the external port interrupts, input-output interrupts and RTC interrupts, timer and software interrupts and Exceptions
(vi) Linking Embedded System Hardware
• Interfacing and Linking circuit for the Buses through using the suitable multiplexers, and decoders, demultiplexers Interface the several system units
design a single phase circuit from a supply point to a load
A JFET for which V A = 80 V, V P = 4 V, and I DSS = 10 mA has a quiescent drain current of 3 mA when used as a common-source amplifier for which R D = R SS = 1k and R L = 3k
Q. Explain working of Common drain amplifie? When an ac signal drives the gate of JFET, it produces an ac drain current. It flows through Rs and produces an ac output voltage t
Q A wire with n = 10 30 electrons/m 3 has an area of cross section A = 1mm 2 and carries a current i = 50 mA. Compute the number of electrons that pass a given point in 1 s, and
Q. A three-phase transformer bank consisting of three 10-kVA, 2300:230-V, 60-Hz, single-phase transformers connected in Y- is used to step down the voltage. The loads are connecte
Q. Explain working of Resistance-capacitance coupled Amplifiers? Resistance-capacitance (RC)-coupled Amplifiers : The following figure illustrates the most widely used method
Passive filters: Passive implementations of linear filters are based upon combinations of inductors (L), resistors (R), and capacitors (C). These sorts are collectively termed
Machine Control Instructions Instructions used to control various machine operations are kept in this group.
Q. Explain polyphase induction motor? The polyphase induction motor operates with polyphase alternating current applied to the primary winding, usually located on the stator of
Using Bode plot calculate (a) Phase margin (b) Gain margin (c) Stability of closed loop system. The open transfer function of the system is t=30/(s+2)/(s+3)Using Bode plot calcula
