b. What is the equilibrium market quantity and the quantity each firm produces?
c. What profit is each firm making?
d. Below what price will firms begin to exit the market?
A linear CW product detector local oscillator has a 500 Hz error while detecting an AM signal. What will the receiver's output sound like What if the receiver is listening to a DSB or SSB signal
1) in a swamped common-emiter BJT amplifier, as shown below, if Vcc =12 V, R1 =8.2 kohm, R2=10 kohm, Rc = 500 ohm, Re= 1 kohm, Vbe = 0.7 V, and B =100, what is the transistor`s emitter current
A calibrated RTD a = 0.0041/°C, R=306.5-ohm at 20°C, and PD= 30mW/ °C will be used to measure a critical reaction temperature. Temperature must be measured between 50 °C and 100 °C with a resolution of at least 0.1°C.
What would be the band gap voltage needed for a material to fabricate an LED that can emit blue light - Design a system for measurements of snoring sounds in heavy snorers using a piezoelectric crystal.
Given the narrow audio bandwidth of a telephone transmission facility, a nominal SNR of 56DB and a distortion level of
Assuming that 1 and 0 bits are equally likely to occur, calculate the number of photons received within each 1 bit.
A 12-bit oversampling ADC oversamples by a factor of M = 64. To achieve the same average power of the quantization noise at the output, but without using oversampling, how many bits are required?
A 100uf capacitor is initially charged to 100V. We want 90% of the initial energy to remain after 1 minuet. What is the the limit on the leakage resistance for the capacitor
Write the expression relating the electrical power converted to the mechanical form in a dc motor. How are the electrical power input and mechanical power output different from these powers?
Sketch the Capacitance-Voltage characteristics for both devices based on part (d) by giving appropriate labeling to the voltage and capacitance axis. You may assume high f measurements.
