Figure P7.54 shows the frequency response Ae(ejω) of a discrete-time FIR system for which the impulse response is
(a) Show thatAe(ejω) cannot correspond to an FIR filter generated by the Parks-McClellan algorithm with a passband edge frequency of π/3, a stopband edge frequency of 2π/3, and an error-weighting function of unity in the passband and stopband. Clearly explain your reasoning. Hint: The alternation theorem states that the best approximation is unique.
(b) Based on Figure P7.54 and the statement that Ae(ejω) cannot correspond to an optimal filter, what can be concluded about the value of L?
Draw a circuit that shifts cyclically a register to left or toright ans is also able to preserve this register's state. Given aretwo controls C1 and C2 that select any of these three operations.use only NOT, AND and OR gates and D type flip flop.
the voltage v in a certain circuit is described by the differential equation 3v"+24v'+75V=0 a) determine the values of α and w0 b) what type of damping is exhibited by V(t)
Mechanical degree is the unit for accounting the angle between two points based on their mechanical or physical placement.
if a computer executes instructions to sum the contents of memory cells 2 and 999 and store the result in cell 0what
If we were to use the same number of bits for all symbols in this set, how many would we need for each symbol. In the parts below, assume we are using a compression method that takes advantage of the relative frequency of each symbol.
You have a laundry room where the following loads are connected to a 208V circuit: 2500W electric base board heater, 600W wash machine, 3600W dryer, and a 1000W iron. All loads are connected in parallel.
Figure P4.1 shows a neural network involving a single hidden neuron for solving the XOR problem; this network may be viewed as an alternative to that considered in Section 4.5. Show that the network of Fig. P4.1 solves the XOR problem by constucti..
Write a program to create an array initialized with Hex digits in the ROM space. The main code should copy this array to a different array in the RAM space.
Calculate the channel capacity and what is the minimum transmission time to required transfer all characters over the channel without error?
The operational amplifier below has a specified input-bias current IIBup to 250nA and a maximal input-offset voltage VOS of ±3mV. It has a unity-gain frequency (gain-bandwidth product) of 1MHz.
At 0°C the circuit is balanced and at this temperature the RTD has a resistance of 200 W. Determine the change in output voltage for a 1°C change in temperature now assuming the meter has an internal impedance of 8,000 W.
