Electronics and Communication Microprocessors And Microcontrollers Difficulty: Medium

Consider a six-point decimation-in-time Fast Fourier Transform (FFT) algorithm, for which the signal-flow graph corresponding to X[I] is shown in the figure. Let $${W_6} = \exp \left( { - \frac{{j2\pi }}{6}} \right).$$ In the figure, what should be the values of the coefficients a 1 , a 2 , a 3 in terms of W 6 so that X[I] is obtained correctly? Each instruction in assembly language program has the following fields: 1. Lable field 2. Mnemonic field 3. Operand field 4. Comment field The correct sequence of these fields is? Digital computers are more widely used as compared to analog computers, because they are Consider the following loop: MOV CX, 8000H L1 : DEC CX JNZ L1 The processor is running at 14.7456/3 MHz and DEC CX requires 2 clock cycles and JNZ requires 16 clock cycles. The total time taken is nearly With the signal generator frequency of a Q meter set to 1.25 MHz, the Q of a coil is measured as 98 when Capacitance C = 147 pF. Then the coil inductance and resistance would be
