Explain Register Direct and Indirect data addressing mode (with examples) available in microprocessors.
Register Direct Modes and Register Indirect Modes:
Illustration:
LDAC R
Here R is a register having the value 5.The instruction copies this value 5 from register and in the CPU's accumulator.
Find the minimum rate of sampling that must be used to convert the message into digital form: (a) If an audio message has a spectral extent of 3 kHz. (b) If a television sign
what is the difference between static and induced emf
Explain the 8259 microprocessor. 8259: The 8259A adds 8 vectored priority encoded interrupts to the microprocessor. This can be expanded to 64 interrupt requests with us
One of the simplest circuits is the asynchronous or ' ripple' counter. Below is shown the circuit diagram of a simple 3 stage ripple counter. The operation of this circuit
To have the same value of P e , show that E b /N 0 in a coherent-ASK system has to be twice that in a coherent PSK system.
If E b /N 0 = 20 in a coherent ASK system, find the value of Eb/N0 that is needed in a noncoherent ASK system to yield the same value of Pe as the coherent system.
Q. Explain Commutator Action in dc machine? As a consequence of the arrangement of the commutator and brushes, the currents in all conductors under the north pole are in one di
Components of PLC There are followings three main components of PLC : a.The power supply and rack. b.The central processing unit ( CPU) c.The input / output (I/O
In this Project you will simulate a Security Alarm system using the Quick flash board. A switch is placed as shown in the figure below. The main goal of this project is: Task 1:
Athree-phase,wye-connected, 220-V, 10-hp, 60- Hz, six-pole inductionmotor (using Figure 13.2.6 for notation) has the following parameters in ohms per phase referred to the stator:
